Are there more files? I only get one small piece from one file?

I also have this issue

I need help. How do I know what size hardware I need? The kit seems like it contains way too many parts for what the instructions show. Tensioner screws, palm screws, elastic bands, and cords? Thanks!

I have not been able to get Thingiverse customizer to work but I found on Thingiverse some instructions on how to use scad to do the same thing on your own pc. I tried it and it worked. Hopefully I can post a link here.

If the link does not work you can search for this on Thingiverse "How to run Customizer on your own computer". I found it very helpful.

How to run Customizer on your own computer
by DrLex

Ran into an issue with the thumb generated in OpenScad. It missed an entire layer, causing a gap and making it fail on that part. Ran it through Netfabb, which seemed to fix the issue. However, when slicing the repaired fingers.stl in Slic3r, it misses the perimeters in one layer (still did infill) of all of the fingers, not just the thumb. Cura and IdeaMaker seem to handle it okay. Just FYI.

Getting this error in customizer: "/usr/local/bin/openscad/openscad: error while loading shared libraries: libCGAL.so.10: cannot open shared object file: No such file or directory"

There is a problem with Thingiverse Customiser. It has been an intermittent error since December. This is a problem their end, not ours.

As this work is so important you may want to set up your own customizer. This paper talks about how to set one up: Free and Open Source 3-D Model Customizer for Websites to Democratize Design with OpenSCAD. Designs 2017, 1(1), 5; doi:10.3390/designs1010005

Hi,
I have the same issue. How to download your 100% scale prothesis ?
Greg e-Nable France

Download the scad file and open it in OpenScad. You need to change the part name near the beginning of the file in order for it to generate all of the parts. You need to type the part name EXACTLY as it shows in the comments, including capitalization. Then render the stl files.

Thank you so much for this comment! Saved the day and my team can work on our next certification! Hero!

Glad I could be of help.

I keep getting an error message from the customizer, don't think it is working... Seems like I'm not the only one with the issues as well...!

I mailed team unlimited and the provided a 11 word cryptic response that there is some disaster instructions posted but I must be crazy as I can’t find it. Cant imagine why they don’t support this - you would think they would want folks involved and helping.

Honestly this almost turned me away from trying to participate But as a work around I found if you try the remix tab most folks have posted their configuration stl files - so if you look around you will find what you need -smile. One mans temp files is another mans gold.

What is the trick to getting stl files? I open in customizer, but the files won't convert.
Suggestions?

Same issue here - must be a system issue

I am unfortunately having trouble downloading this file from the customizer, is there any advice?

Thank you, Thank you , Thank you

I would like to print this but I'm a little confused, when I look at the files all I see is one .scad file. I tried loading that into s3d and nothing happened. Can someone please let me know how to print this, thanks!

Printed and assembled all the parts. Everything pla and pins in petg. Found the pins a little too easy to remove. Can I use a bit of super glue to set the pins? Not sure if it's allowed or not.

Hi, do you know why the page for unlimbited arm is no longer available? it used to be here - https://www.thingiverse.com/thing:1672381/#comments
Thanks

The UnLimbited Arm v2.1 - Alfie Edition

Can the hydroforming jig be printed without supports? And should the proximal side (the bottom) be on the build plate or should it be printed vertically?

Using PLA, 2 shells, 10% fill, I did not need supports using a Makerbot Replicator 2.

Can this be uploaded as a STEP file?
I use Solidworks and don't need another CAD program.

I am printing this now at 25% infill. I used 5 shells for strength. Is this unnecessary? What shell count is recommended?

I'm using the openscad software to open the file to convert to .stl.

Thing is I'm only getting one part.

I cant find the other parts.
I see there is only one .scad file and when i open it I'm only seeing one part?

Any ideas on how I find the others? Thanks so much.

did you ever get this figured out? I am having the same issue

i used openscad too. it renders one part at a time. you have to edit the file to change which part is rendered. the parameters are listed right at the top of the file and there is just one place for you to change the parameter; it's very clear once you open the file and look at this section.

i rendered all parts at 120% from the openscad file without issue just this weekend.

Hello! The Phoenix hand is a great idea, and I'm trying to learn to print them, but having some challenges. I used Customizer to create STLs for right hand, 120%. But in the Thumb element of the Fingers group, there was a triangular gap in the shape. I was able to fix this with Netfabb, which reported there were "flipped triangles".

But now I'm struggling to print without supports, parts keep coming loose even though my bed has strong adhesion. Finally spotted the cause -- at the overhanging tips of the print, they are curling UP (not sagging down as I would expect) and this snags the nozzle or the proximity sensor, knocking the part loose. Here's a photo of this -- I stopped the printer (Prusa i3 Mk2) mid-print:
http://markleavitt.com/blog/video/PhoenixHandPrintProblem.JPG

It's blurry but you can see the ends curling up. Does anyone have advice for reducing this effect? Are you all printing with or without supports? Thanks!

Update: turns out curling at overhangs is a familiar problem on the Prusa i3. I reoriented the print so the troublesome tips are along the X-axis, slowed the print speed to 70%, and got through it this time. Onward!

Hola buen día o buenas noches desde Argentina "Patagonia" consulta existe el .stl ?

Some of the makes here say they printed without supports - I find it hard to believe you can print the palm without supports.

Yes, we have printed the palm without supports, but there might be some cleanup needed on the inside/underneath of the palm afterwards.

What is the recommended infill percentage to make this the most useful in PLA? Layer height?

We use simplify 3d honeycomb infill at 25%

Are we not supposed to use supports at all?

Hello,
I printed all the part and am now assembling. Everything fits perfectly.
Howerever all the assembly guidelines as well as YouTube video's show hands using a whippletree. That part is not created in this version.... so how do I assemble the last part of the hand using the box in these files instead?
Thanks for the help

There is no need for the over complex whippletree with this version; as it uses the three pin partial tensioner system.

How do we assemble the three pin partial tensioner system?
Thanks

Please see new image showing wiring.

Thanks for the answer. That still leaves my last question: how do I assemble the last part of the hand using the box in these files. Are there any guidelines or tutorials?

Please post on how to assemble the last part if you find out. Assembling without the whippletree. Tutorials only show with it and not with the three pin partial tensioner system. Much appreciated

I'm using the openscad software to open the file to convert to .stl. Thing is I'm only getting one part. I cant find the other parts. I see there is only one .scad file and when i open it I'm only seeing one part. Any ideas on how I find the others? Thanks so much.

You must use the Customizer to get all the parts at the correct scale and to choose left or right hand.

How do you scale this? What are the dimensions in 100% in order to scale?

Wrist to fingertip is 135mm at 100%

How can I get it in .123dx format?

This file needs to be broken into multiple files, as the individual parts are actually embedded in the one .scad file.

Again -all- parts for this hand are in the single scad file, but editting of the file needs to occur to choose which part to print.

You can also use the customizer to get all the parts out as an STL. You choose either a "right" or "left" hand and the scale you want and it will output all the STL's as a new thing. Pretty nifty!

If you insist on using the openscad file rather than customiser then you need to change which bit of the arm it's generating in the "part" variable.

part = "Palm";
part = "Fingers";
part = "Phalanx";

etc
