Featured Thing!

Description

All files can be found under the "Thing Files'' tab right below the photos of our hands. Please click download all file to get all components of the hands.
For More information on assembly or the research, please go to http://www.cyborgbeast.org

To make the Normal Hand Version, print and scale the following:
1x Right OR Left Palm
1x Normal Gauntlet or Normal Gauntlet w Tensioner
4x Finger Phal
4x Finger w Bumps OR Finger wo Bumps
1x Thumb Phalange
1x Thumb Finger w Bumps OR Thumb Finger wo Bumps
To make the No Thumb Hand Version, print and scale the following:
1x R No Thumb Palm OR L No Thumb Palm
1x R One Hinge Gauntlet OR L One Hinge Gauntlet
4x Finger Phal
4x Finger w Bumps OR Finger wo Bumps
Ulnar/Radial Deviation Hand, Movable Thumb Hand, and Cyborg Arm --> Soon to be released.

3/2/15 Snap Normal Hand is now added! Note: Gauntlet does not have tensioner block yet, will be added soon. Everything is compressed in the Zip File (Snap CB) for ease of downloading

Most voluntary closing devices including this design need sufficient wrist movement and strength for proper function. This design doesn't require Orthoplastic. The fingers are designed for better gripping and to avoid over extension of the proximal phalange and distal finger segment. It fits a 1 to 2 mm cabling and elastic bands.

We printed the right palm.stl and parts of it did not print. All the other parts printed fine. We are using a Dimension SST 1200es 3D printer. When I looked at the .stl file in my preview/setup software to prepare for printing, it appears there are slices of the right palm.stl missing, so when it prints, there are parts missing. Could you send me an updated right palm.stl or even the CAD file of the part?

Where am I supposed to get the hex tensioners that fit with the gauntlet?

I noticed soft rubber looking finger tips in the photos, where do these come from?

Instructions

Assembly instructions can be found on the website http://www.cyborgbeast.org
Printing Instructions:
Infill: Depends on age. We usually do 30% infill.
Number of Shells? 2
Temp? Depends on Plastic recommendations. But 230 c is safe estimate for all types.
Speed? For better quality, lower your speed to 60mm/sec extrusion and 90mm/sec for traveling
Orientation: The same as the objects load onto the build plate. We designed the STL files for ease of use so you do not need to change much.

See Manual as a PDF files.
Jeremy Simon made a very instructive and educational videos for the assembling and testing of the Cyborg Beast. Thank you to Jeremy Simon and 3Duniverse.org.

I noticed soft rubber looking finger tips in the photos, where do these come from?

I am trying to print this off for a school project and I am wondering what the dimensions would have to be for this to fit a person comfortably and how much it can lift and endure.

Download the "Cyborg Beast Instruction Manual" PDF file https://thingiverse-production.s3.amazonaws.com/assets/80/10/0d/92/5a/Instructions_Cyborg_Beast_Updated__6_26_14_.pdf That contains instructions on scaling the parts to required hand size, measure across the knuckles of the non-affected hand and place that value in the equation detailed in the PDF file or even the hand-o-matic http://webapp.e-nable.me/ selecting the Cyborg Beast model.

We made a hand that was 127% original size. PRO-TIP: Tensioner ended up working best at 100%, despite our hand being at 127%.

Probably because the holes don't scale as well as they should.

try 2.

Several of the hands and the instructions say there are slots in the gauntlet STL... but no where in these STL's is there a gauntlet with the slots? Can u please provide that file or some direction to where I might get that file?

Sorry we are very busy updating and designing new types of devices. As far as the picture of the old gauntlet, we removed that gauntlet due to replacing it with a much stronger version. You will have to drill two holes and use chicago bolts to attach the velcro on the top (Not sides) of the gauntlet. Sorry for the delay.

I was wondering when you would be releasing the arm .stl file for the Cuborg Beast?

It can be printed on the XYZ da vinci 1.0 printer?

Yes it can!

Thanks a lot jorge so Im going to buy it :)

It can be printed on the XYZ da vinci 1.0 printer?

Sorry, I found the note regarding the yet-to-be release of the ulna and radius version; but would still like some tensioner info.

Do the files include all the various modifications? Specifically for the beast with the "complete" wrist movement. And can someone post a link for a source for the dial tensioners?

Thanks in advance:)

The tensioners is a modification we use in our research. We get them off of snowboard and ski boats. There are files that have a separate tensioner block that is 3D printed. You can see them in the digital designed photos.

Hello, What strength of nylon cord would you recommend using? I'm thinking about using 50lb braided microfilament fishing line. Would that be strong enough? Thanks!

That would work very well! We are currently using just a nylon braided cord.

Soz for being newb - but I read the news article about the Cyborg Beast and it touched me. I'd like to help out and further my knowledge about using 3D printers. I can splash out a little and was wondering what size Makerbot printer should I buy to make a child's Cyborg Beast hand? I was considering buying the fifth generation desktop printer. Thanks.

We have printed these hands on the makerbot printers (replicator 2 and 2x 4th generation). We also have had great success with the ultimaker 2

Jorge Great job, Thanks for sharing this

Is it true a Malaysia press report this is a cooperation between enablingthefuture.org with local companies in Malaysia named pebblereka.com? In the newspaper report it was stated that the mechanical hand (prosthetic devices ) was design by pebblereka.com.

It is also stated that the cost is MYR300 - 500 (usd 90 - 200) for children ages 12 years and over.

Enablingthefuture.org should email the editor to avoid confusion and clear the reputation of the good name of this organization because I know you are working voluntarily to the world community. Thank you

Question: What scaling factor would I use to print this out for a 40 year old? I'm trying 150%, but does anyone have any ideas?

Hi Solomondg! Generally when we are making a hand for someone, it depends on the size of the affected palm. This way the hand fits correctly. Also, compare sizes to their non affected hand. We have made a hand for a 26 yr that was 180% but he was a much taller person. Hope that kind of helps out! Let me know if you have any questions though!

how do you convert the file to gcode to print it

You use the STL files with the slicing program that came with your printer.

FANTASTIC! I have printed several hands, various sizes to experiment. I can't seem to get any size to work with Chicago Screws. The screws seem way too big for the hand. I purchased all of the recommended sizes of the screws but they don't fit. I drilled some of them to be bigger but they either cracked the plastic or were so tight that the fingers did not bend. Am I the only one with issues related to the Chicago screws? Anyone find something better to use? I won't be using the hand for a real person - we are using in an engineering class focused on adaptive technologies and prosthetics.

Hi Kmaxey,

You do need to drill out the holes for the Chicago bolts to fit correctly. If you use a #4 drill bit and just drill slow, then you should be good. Depending on the size of the hand, you may need to use smaller drill bits first so you don't take out too much plastic out at once. Don't force the drill, let it due the work. Let me know if you have any more questions!

Hello there, i will be sending this to the printer tomorrow for a five year old kid, got the scaling done, but when im looking through all the files i can seem to get the tensioners. Can anyone mail this to me, You can mail me on [email protected]

Thanks Artie

Hi Artie, What tensioner are you having trouble with?

Hi JorgeZuniga, I've managed to get it , my apoligises, Thanks for replying

Hey Jorge!

Have you thought about making a elbow mount? for those with no hands? Would definitely be interested in that.

Hi Nekard, We already have that design done. We are just finalizing the files and will be posting those on here shortly.

Hi Jorge!

I'm on a student senior project team working on designing, building, and testing a prosthetic hand for an active duty Navy SEAL. We were wondering if we could have access to the original Solidworks files so that we can make modifications for the open source community. It would be much appreciated!

Thanks, Michael

Hi Michael, we are not releasing the solidworks/fusion files for this, just the STL. But you can make the modifications in the program called Blender.

Hi, Thanks for your work to get this up! Where are you getting this dial type tensioner? You may want to put it in your post.

Thanks

We are getting them from old ski/snowboard boots.

hola soy de Colombia y quisiera saber en que programa puedo abrir el archivo para poder imprimir la mano.... gracias

hello can anyone help me 3d print? my wife is 27 and has had abs from birth, I would love to make this for her! if anyone can help me please contact me through email on [email protected]

Please let me know if you have not found anyone to print the components

I can't download the .pdf instruction manual- can someone email it to me? [email protected]

Should be able to now =)

Hola Jorge, Primeramente te mando un saludo desde México y una felicitación por tu trabajo. Hay manera que pudieras compartir con nosotros con que configuración de slice hiciste la impresion?

I am lost on what settings to use... I am using a Makerbot Replicator 2. What I would like to know: Infill?

of Shells?

Temp? Speed? Orientation?

Did you get a response? I have the same questions.

So sorry for the long wait!! Here is the information Infill? Depends on age. We usually do 30% infill.

of Shells? 2

Temp? Depends on Plastic recommendations. But 230 c is safe estimate for all types. Speed? For better quality, lower your speed to 60mm/sec extrusion and 90mm/sec for traveling Orientation? The same as the objects load onto the build plate. We designed the STL files for ease of use so you do not need to change much.

Also, what do you estimate the cost of the plastic to be and if anybody knows the approximate weight of plastic being used, thatd be great. sorry for the specific questions. i am trying to get a sponsor for our team to print these.

The cost of just the plastic is about $10 at about 30-40% infill. We have used 3mm and 1.75mm plastic both abs and pla and other types as well

hi jorge I am a student of biomedical engineering, I am from Colombian and I would like to know which software you use to create these models.

thus to contribute to designing mine have some experience in cad software, autocad use but is a bit complicated to work with this software these so I like to know what software you use to do better and so to perform best design

Thanks for your attention and I hope I can collaborate

Hello. We used Blender for this design. Take care p_munar!

Jorge, me puedes contactar a [email protected] gracias mil

Hello Jorge, thank you very much for all this information. I would like to help our people in Colombia so we create a foundation called imprimiendo suenos. I have just a small printer XYZ da vinci. Can i please have this files on stl? i am donating every thing regardless country, age, sex, etc. but i need stl files. thank you so much nuevamente gracias por toda tu ayuda

Los archivos son casi todos stl, lo que pasa es que estan en zip folders.

Hi JorgeZuniga

I am helping someone 17 years old with one thumb on right hand I cant decide which one to print "Cyborg_Beast_Thumb_Cut_Out_1.45_07-1-14" or "No_Thumb_Palm_One_Hinge_Gauntlet"?

Looking at the scale chart I see that it goes to 16 age and stops. Should I be scaling with %145? And I wonder about fingers; there is only one finger file. Are all the fingers printed in same length? And when I scale a finger with %145 it gets to a length 57,80 plus phalange scaled. Isnt it a bit long finger Am I doing it wrong?

I know its a lot of asking here :)

Thanks Serdar

Hello Serdar You need the Cyborg Beast thumb cut out and the no thumb palm one hinge gauntlet. Let me know if have need help scaling it. how did 145% work?

hello thank JorgeZuniga i try new design but files CB_1.45 gauntlet (tensioner).stl i cant print with new design i user replicator 2x pl accept to group my email is [email protected] thank

Hello Neovn. The new gauntlet is not printing? Can you specify the problem? Thanks

Are there any CAD files for the design (Solidworks, etc.), for more control over scaling, or are there only STL's?

Sorry for the late response. We have posted the STL, but also the Blender files.

Some people in Argentina(3dlab&fabcafe) are saying to the local media they are the designers of this.... And they are trying to make a great Hipe. I haven't seen any media or interview where they state this project is this or at least was used as basis every picture is identical to this design. They state Gino tubaro is the designer! Can you believe it??

I have talked to Rodrigo and Gino about this issue. I'm from Chile so I'm familiar with the media in Argentina and the rest of South America. I hope our online community, like you, can provide the correct information to people. Ahntlia thank you so much for your help. As long as people are getting this device at no cost who cares who designed it. Take care and thank you again for your help!

26 Soon to be leaving thingiverse because of Makerbot's behavior towards open source. Details: http://www.fabbaloo.com/blog/2014/5/25/has-makerbot-crossed-the-line-for-some-yeshttp://www.fabbaloo.com/blog/2...

Thank you for the info!

Buenas tardes Jorge, espero que hables Español (Spanish), descargue los archivos STL y los cargué en el Objet Studio de la Impresora Eden260V de Stratasys, pero al validar el stl del archivo "Left_Palm_Cyborg_Beast_7.0", me aparece que este se encuentra abierto, trate de repararlo con netfabb-basic_5.1.1 pero el error persiste usted me pdría ayudar con este inconveniente?

Hola Ayer pusimos unos archivos mas recientes "Cyborg_Beast_1.3_Marc Petrykowski_5_29_2014". Nosotros arreglamos 523 de 587 non-manifold vertices que estaban abiertos. Si el error persiste click continue en tu programa or ignora el error. Espero que esto te ayude!

Hi guys, I just download the stl files, but the gauntlet come with no hole to fix the palm, is this correct? Will I drill it ?

We can help you with that. Just contact us via http://enablingthefuture.org/http://enablingthefuture.org/

Hello. Great job this will really change the lives of many people. Questions. I want to print one but I have doubts assembly. What kind of wire is used for tensioning? is some elastic thread, is is common thread? Thank you very much Greetings from Argentina

You need elastics and nylon strings (the same used for curtains). And yes it's common. Especially in DIY jewelry shops. (Or http://taobao.comtaobao.com or http://alibaba.comalibaba.com if you are comfortable with China AND/OR adventurous)

Thank you Kolia!

Hello I am using a uPrint Pro to print the right hand model for a young girl in my area. I am having an issue with the right hand and the fingers, for now these are the only issues. What happens when I go to print them is the bottom portion of the hand, anything after the top curvature is dropped from the print. The issue with the fingers is the tips are not part of the finger, it puts support between the tips and the finger. When I clean the fingers, the tips are seperated from the main finger piece. Glue will fix the issue, but I would like it to actually print out whole, as I believe this is how it was designed to be, as one piece. Any ideas or reasons as to why I am experiencing this issue? I have looked through most of the comments and I did not come across anyone else having this issue. I will dig deeper to see. Thank you for any help you can provide.

I tried using the files within Peter Binleys Fix, and it came out worse. Are these designed only to print with MakerBot units? The original 'Robohand' printed fine. Thank you for your time.

Hello zelbst We have some other users with a similar issue. My guess is that the issue may be related to slicing the files. We have no issues with our MakerBot units, but we want everyone to have a good experience. Have you tried the files we posted yesterday? Marc has fixed some of the open mesh. Sorry for the late response zelbst.

Is it possible to get the original files ? or STEP file. ?

The Blender files are posted on a zipped folder.

You mention that you added the right palm, is it any different than just mirroring the left palm ? (what I did in Cura since I wanted to print a right hand).

Yes! we just mirror the left palm.

hello, i'd like to make this, but I haven't done like this, so could you tell me how to open these file? i have done google, but i couldn't way to open this. only i can understand is i have to install Blender. but is this enough to print them by 3Dprintar? i am very sorry, but if you could, it'd be most helpful

Hello Yuh You don't have to install Blender. Your 3Dprintar should have a software that will open stl files. So go to the software for your 3Dprintar and open the stl files from there.

Amazing what a brilliant idea my hats off to you sir all of you :)

Where can I get more info to get one started for my 19 year old son and what cost it would be?

I just wanted to say thank you guys so much for providing this design to the community! Can't wait to try this out. Take care!

Thank you daudside.

For others stepping by: a few comments about printing (in PLA here) from what I read and experienced:

  • You probably want to print the fingers and phalanges on their side, so that the layers are not in the exact directions of the constraints when the hand is used (do you see what i mean? less risk to delaminate). On the other hand (:-p) , doing this will degrade the pointy tips of the fingers and the side which will be supported. Up to you to decide what you want, fancy looking or more resilient. Unless somemone has a printing orientation that fits boths?
  • The gauntlet can be printed without any support, vertically.
  • For the palm i didn't find better than printing it with a huge support under it. And it was a pain to remove afterwards, but didn't find other option. Any idea?
laird - in reply to Kolia

That's how I print the palm as well. One thing that helped is using Simplify3D as a slicer, as it generates support that's easy to remove. In particular, it can leave a one layer gap between the support and the supported material, so the palm ends up resting on top of the support, not bonded with it, so the support is quite easy to remove. The other fantastic thing about Simplify3D is that you can manually control where it generates support, so you can (for example) generate support for the arch of the palm, but not in the screw holes and bridges over the knuckles. The result is that the print is very clean, and the support is easy to remove. The newer versions of MakerWare also do a pretty good job with support, but IMO Simplify3D, with its manual controls, gives the best results.

Thank you Laird!

Kolia - in reply to laird

Thanks Laird, I will give a try to Simplify3D ! I've always used Cura exclusively so far (Ultimaker sect :-p) However it also allows to put a gap between the support and the part... but maybe I've been too shy and i need to increase it. And no way to choose where to put the support. Interesting.

Hello, is there any way to extend the device so it emulates a portion of the forearm? im missing my left hand and a portion of my forearm and was interested in getting this printed. but if its only designed to be a prosthetic for the hand it might be too short.

Hello 952pin. I'm a core member of e-NABLE (http://enablingthefuture.org/)http://enablingthefuture.org/). There are a group of folks at e-NABLE trying to accomplish this task. Robohand (http://www.robohand.net/)http://www.robohand.net/) has a system in place for the entire arm named "Roboarm". They also posted their files here in Thingiverse (http://www.thingiverse.com/robohand/designs)http://www.thingiverse.com/rob....

Sorry not good at this , to fit over a hand to help with grip strength ?

Hello Chomie51. At this point that will be difficult, but our team is developing new devices that may help those with arthritis. We are at a very early stages, but will keep you updated.

No, for children and people missing fingers. To replace the hand.

Jorge, I have a daughter who has serve arthritis and can't away uses her hands. My question is could your hand be modified to f

(If I may: the thing info is very confusing, it's hard to figure out what to print together in the thing files after, not clear if everything is compatible or if they are some set) Working on one RIGHT NOW! This is brilliant, and the eNable community too. Made my week.

Thank you for your feedback Kolia. As soon as the semester ends I will organize the files and the description. Please feel free to propose any organization format. Thanks again!

The last .zip set with the version 1.2 is exactly what was missing when I posted my initial comment. Much easier to sort out what (the latest) to print like this. Thanks! (well, except now i feel I want to re-print this latest set :-p )

There appears to be a facelet normal problem with one of the facets in the right palm. I got an error whilst opening the file in SolidWorks & in FormLabs PreForm 1.3

I will ask Marc (my research assistant) to work on this issues. We will keep you updated.

A 3d printer in every school to create the next set of entrepreneurs and a new workforce in the long run. This will allow the students to fail on their inventions, refine, fail refine and accept failure is a great thing... While we are ate it have them make projects like this hand for disabled people. Yes this is certainly the direction we need to go.

First let me say that this is an awesome remix! My son is incredibly excited to see this design, th eonly problem is that I can not get it to print. I have tweaked settings on my Makerbot 2X and the build keeps lifting off the platform. I have tried printing both with and without rafts ad/or supports and each time at about 5%-7% of the print it starts to go haywire, spewing out spaghetti. I thought maybe it was my printer, but I have successfully printed other objects that I have created or downloaded from Thingiverse. Any help and or suggestions on how I can get this to work would be most appreciated. I have spent all weekend trying to get this done as a project wth my 11 year old, but so far am not successful. Thank you!

Hello mflynn What files are you using? We recently updated the files, so perhaps that may be the problem. If you let me know I can print those files on my rep 2x and see if I encounter the same issues. You can always try different files to see if it works. The rep 2x sometimes gets really temperamental.

I'm having trouble printing the Finger_Screw_Key file. The hex wrench piece doesn't appear to be flush with the build plate, along with the finger and screw.

jorgeee, muchasss graciass creoq ue pude resolver el problema, lo que hice fue descargar la palma izquierza y esta si estaba bien y lista para imprimirrr, graciasssssss por la ayuda

con respecto a lo que te comente, la parte Right_Palm aparecia con un color oscuro mientras que las otras partes aparecian normal en un color mucho mas claro, y creo que aunque la palma esta en archivo stl no es compatible con la impresora zprinter 150 y quisiera saber en que prgrama la hiciste y si me puedes enviar el original y tratar de nuevo para ver si la impresora lo imprime, aqui te dejo mi correo ([email protected]), me seriaaaa de muchaa utilidad si me pudieras responder para mañana viernes 28 antes de las 5. gracias

hola jorge buenas noches, te hablo para darte las buenas noticias de que acabo de imprimir la mano en una impresora de la marca zprinter 150, pero paso un problema, todas las piezas salieron de maravillas en la impresion pero no se imprimio la parte
Right_Palm, en que la diseñaste?

buenas tardes amigo....realmente lo felicito por este maravilloso prótesis... realmente estoy interesado en imprimirlo en mi maquina 3D....ME GUSTARIA POR MEDIO DE SU INVENTO OTORGARLE SONRISA Y APOYO A ESA GENTE QUE POR ALGUNA RAZON NO TIENEN SUS MANITAS COMPLETAS...REALMENTE LO FELICITO POR TAN MARAVILLOSA CREACION.... Tengo un problemita....me he descargado todo los archivos pero en mi programa de impresión me dice que la piezas no estan completas y por ende no puedo imprimirlo... tengo una printrbot simple 2013 y utiliza filamento pla... me gustaría que me ayudara en esto.. saludos

I'd like to know if the materials are waterproof, because i'd like to make a prosthetic to use while I surf or for swiming. Thank you so much for your dedication, great job.

PLA is not water soluble.. It will be fine in the water

In the instructions, it says to "Measure the knuckle area" - Can anyone please clarify what exactly this means?

I'm guessing this refers to the distance from the small finger to pointer finger at the biggest knuckle (e.g. D2 to D5 MCP joints). Thanks!

You can find a complete explanation in the user's instructions of the Snap Together Robohand, page 4. I think it is the same process. This is the file: https://thingiverse-production.s3.amazonaws.com/assets/30/48/5d/92/b1/Snap_Togeather_Robohand_Instructions.pdfhttps://thingiverse-production...

What exactly is the "Z" for on the hand? Just wondering if Shea wanted there or something.

Jorge, what do you think of incorporating something like this http://www.thingiverse.com/thing:274411http://www.thingiverse.com/thi... over the lines where they run across the back of the hand? It looks like there's room. Nick's idea was that if the lines were locked down, then the fingers would be held in place and people could (for example) maintain grip on things without having to keep their wrist pressing at an angle. What do you think?

What are you software are you guys printing with?The palm is lifted off the bed for me because of the the slightest bit of the thumb hinge. This actually adds a number of problems to the ease of printing with a couple free slicers I am finding. Full support on Slic3r fills the holes and is overkill, Cura for me has it's own problems I am trying to work out. Wouldn't so many more people be able to print if it were at least a flat base to start out with instead of floating in the air?

I'm having similar issues with pieces being lifted off the build plate. Any solution?

I'm having the same problem.

I did find a solution actually. Using CURA, in the advanced settings there is an option to "cut off object bottom" it lowers the object by whatever .mm you enter. I dropped it 2mm and printed much easier.

Has anyone tried parachute cord? I know sjcoledesign mentioned kevlar Cord but I don't think they are exactly the same. Parachute cord is cheaper, it is easier to find, and has many colors.

Hello Jeremy I included the video on the instruction section of this thing!

Is there any way for me to be able to get the original cad of this ?

It was done on Blender. For further requests joint our e-NABLE group:

https://plus.google.com/communities/102497715636887179986https://plus.google.com/commun...

Very impressive variation. I made a similar version but not as organic. Your's is much more aesthetic. One suggestion. Lose the fishing line tendons. Use kevlar cord (aramid fiber) because the fishing line has some stretch to it. Kevlar is extremely strong (bulletproof vests), has virtually no stretch and is extreme flexible. Look for it on ebay, model rocketry enthusiasts use it for the parachute cord.

Unfortunately, unprotected Kevlar is highly prone to UV degradation.

Thank you! I will try Kevlar.

Good work, any advice on sizing for different kids, people, etc.?

Wow! THAT is awesome. I love the revision. You are going to make a lot of people in need happy with this. Grats! Heck it looks so cool i want to print one just as a toy :P

ive been stalking hands on thingiverse for a bit and so far this has the best design that ive seen! but an issue im running into is that the person i would like to print this for still has a thumb and a partial index... (have pictures if desired) i am thinking i can "delete" the thumb from the file, but i dont know what to do about the partial index. what he has left is about halfway up to his first knuckle on his index. will this effect the wear or functionality of the device?

How many grams of plastic does this take? Also, when xyzware is released (http://us.store.xyzprinting.com/)http://us.store.xyzprinting.co..., it would be great if you could upload to that as well. Great invention by the way!

That is a good question. I don't really know. I will find out and post the requested information.

Has anyone tried to design the screws. I'm thinking that they don't really need to screw. Two pieces that slide together and add some super glue keep them together. I will try to design it. My goal is to show one off at a Maker Fair, but finding the right size appears to be difficult, unless someone can provide a source. This will be a demo that shows what is possible. Maybe I will get an opportunity to actually print one for someone.

That is a great idea. I made some without thead but they broke right away. I will try Nylon this time!

I created a replacement for the Chicago Screw. http://www.thingiverse.com/thing:266673http://www.thingiverse.com/thi...

You can open it in the Customizer, but it has limited options. If you open the .scad file in OpenSCAD you can change the parameters to any size you want. I posted a picture under “Made one” on the site. The hand held up to kids at the Nova Mini Maker Faire, so it’s pretty sturdy. If I were to make one for someone, I would order the Chicago Screws. However, this would be good for prototyping and sizing.

I made a replacement for the Chicago Screws. They held up well at the Nova Mini Maker Faire. http://www.thingiverse.com/thing:266673http://www.thingiverse.com/thi... There are limited options in the customizer, but they are completely customizable with the .scad files. The ones I made were 3.5mm for the outer sleeve. They are at least good during prototyping. If I made one for someone, I would order the proper screws. But these would be good to check the fit and function.

I want to make this hand, but i'm not using makerware. And my slicer is having problem do to holes in my mesh

Have to try meshlab to repair those holes?

El washer va en la muñeca. necesitas dos en cada lado. El Finger es mas largo que el Thumb. La falange del thumb es para el thumb (dedo gordo) y la falange del dedo (Finger) es del dedo. Tu puedes mezclar las partes, el diseno esta hecho para ser creativo! Cuidate!

como funciona la parte llamada, donde va ubicada? Washer.stl

y cual es la diferencia entre el (Finger_CyborgBeast6.4) y (Thumb_Cyborg_Beast) es que uno es mas grande que el otro? ................. la parte llamada (Thumb_Prox_Phalange_Cyborg_Bea) encaja bien el todos los dedos (Finger and thumb_CyborBeast) o solo se usa para unirse el pulgar con la Palm o pude usarse para unir todos los dedos, lo pregunto por que en las imagen vi que solamente usaste el Thumb_Prox_Phalange para hacer la uniones de los dedos y no usaste el

Proximal_Phalange para nada.

hola Jorge Zuniga, quiero felicitarlo por su dedicación y el expLendido trabajo que ha venido haciendo con este proyecto, y poR estar siempre al pendiente de todas las preguntas, de todos sus compañeros y de todo el trabajo que juntos hacemos. GRACIAS

Hello Mararuo That is the intention. Do you have any advise?

To jump in, I am working on "porting" the Talon design (not my design) into OpenSCAD specifically to make it parametric, but if you're interested in making Cyborg Beast parametric, I'd be interested in working with you to port it into OpenSCAD. It's a beautiful design!

There are many options for making designs parametric. The most popular open source parametric modeling tool is OpenSCAD. And it's used in Thingiverse Customizer, which makes it very easy for people to use parametric designs to generate personalized things.

That being said, OpenSCAD is a programming language, not a GUI modeling tool, so it's a very different kind of tool than, say, AutoCAD or Rhino, which are also parametric.

What do you need laird? The original files? Let me know.

That would be great. What did you do the modeling in? Starting with that, I can see what formats and approach will work.

The first Robohand was parametric, do you plan on doing a parametric version of your absolutely amazing design?
