Since the thingiverse needs good robots to fight the bad ones, i give you R2! I've modeled the full scale version in inventor and put the files here. I've also made an attempt to make it printable. However, since my printer is currently down for repairs, i'm hoping someone else will give it a shot and let me know how it goes!

Obviously design credit goes to lucas film, but the 2d design files came from the r2 builders group, and the 3d is the result of days and weeks of modeling and guessing. May the force be with you :)

So I made this flying saucer (http://www.thingiverse.com/thing:10428) with a working hatch and everything, but there was something missing: little green men to pilot it.

So here you are, little green men made in OpenSCAD. There are two variations, sitting and standing.

Update: added a tiny version that should fit in the saucer with the hatch closed.

I saw a pair of portal earrings someone else did and decided to make my own version. based off of the Portal 2 game logo.

This is the first release of the Boot-strappable Open Laser Cutter project that I've been working on for the past few months. The goal of the project is to construct an open design laser cutter with a large cut area (about 1 meter square), for about 5%-10% of the cost of a commercial system. The design draws heavily from other open laser cutter projects out there (such as the Buildlog 2X Laser Cutter) in using inexpensive aluminum extrusion and optics for most of the structural frame, while here most of the custom parts are 3D printed from ABS.

The printed parts represent about 10 hours of total printing time on a Makerbot or Reprap, and have been designed with the hope that they would be of general utility to anyone printing out a large CNC system -- not just a laser cutter. These include parts such as NEMA17 motor holders that mount onto t-slot, idler brackets, pillow block bushing mounts for motors, idlers, and shafts, and so on.

This is my take on a smaller reprapable version of the Ultimaker. I was going to wait until I had it 100% working but there have been a few gantry systems posted and I wanted to get it out there. Here's a list of the current inspirations, I'll add links later: Ultimaker, brutestruder, bowden cable, mendel bearing setup and Makerbot.

The printer's external dimensions are currently 8.5inx8.5inx10in and the build area is 100x100x175mm.

The main reason I started working on this is most printer designs that have been coming recently have been getting larger in footprint. I want something that'll easily and conveniently fit on my desk, I also have no problem with the 100mm square cupcake build envelope.

Where I'm at: I have had problems with friction in the gantry and am in the process of redesigning all of the moving components. I would upload files, but I just trashed them all as not good enough. So, you'll have to wait until they are good enough. That being said the printer in the photos can easily do around 30mm/s. I just want better.

Here's a couple answers to questions that I know I'm going to get:

Yes, all of the parts fit on a makerbot.

Yes, there are diagonal supports that are not in the photo.

No, it's not a fab at home derivative, I haven't seen the workings of that until yesterday. (Has anyone else actually read the Stratasys patent from 1992?)

I attached an edrawing if people want to look at it. I'll post an stl of the full assembly later.
edrawingsviewer.com/index.html

Yes, that's a Makergear compact plastruder head. It's just so small, it fits perfectly. The new version will have two heads whose nozzle tips will be 18mm apart.


About timeframe, looking back on the last 3 months, I've (spent way too much time screwing around with the Makerbot) wife's quote. Now I have to get some real work done since screwing around on the makerbot doesn't pay the bills. I would expect something in a couple weeks.

Update: Here's a link to a video showing the new center gantry unit for the MiniMaker.

Update: Working on minimaker2 right now, here's a video of the X-Y gantry running a calibration cube at 400mm/s!: flickr.com/photos/48982649@N07/6550391991/in/photostream

Here is a motor with a v8 configuration. It is two halves mounted ninety degrees from each other with the same crank shaft, connectors and pistons as the four cylinder just more of them. It is worth noting that they can be alternatively mounted flat or opposing piston configuration. I opted for the muscle of the V8!

I have added the crank shaft parts layout and the source file as separate files so if any parts brake, you don't have to print the whole thing again!

UPDATE: I have uploaded the fixed STL files, no more errors from Skeinforge! Thank you all for your valuable input as I am still learning too.

I have added a larger piston file but it requires good printer settings.

Ribbit. Ribbit.

My daughter wanted a frog. Here it is for anyone else. I have included the file in other 3d formats for people to play with.

This is an electric motor made from a printed circuit board, some 3D printed components, 44 magnets, 44 steel washers, and a handful of electronic components for drive circuitry.

It is similar in design to thingiverse.com/thing:802 but it is much easier to make and the performance is much better. Maximum mechanical power output is about 600 mW. Top no-load speed is about 2000 rpm. This is probably enough power to do something useful.

Also provided is an open source script that runs on Matlab or GNU Octave to generate custom motor coil patterns. The script will export CAM files in KiCad or EAGLE format, so you can fabricate coil patterns of your own liking.

While this motor used a commercially produced PCB for the coilplate, the idea is that users can produce functional motors using nothing more than their own 3D printers.

See reprap.org/wiki/Automated_Circuitry_Making for an overview of using Reprap-style printers to fabricate circuit boards.

I think we can all agree, life would become much more interesting if I launched a turtle shell at you every once and a while.

But it’s no fun if I’m the only one with a shell to launch. Therefore…

Turtle Shells for Everybody!!!

All you have to do is print it out and assemble!

The Turtle Shell Racer is as fully 3d printable as I can make it using my Makerbot Cupcake CNC and its MK5 Extruder. The pdf file contains full assembly instructions and a parts list. This is a very ambitious project; expect to spend some time on it.

UPDATE Sept 26th

I have uploaded the modifications I made to the shells for the NYC Maker Faire.

Wheely Bar.stl - This replaces the rear axle brackets.stl with a wheely bar, which allows awesome wheelys!

New stearing Link.stl - This new link replaces the old steering linkage.stl. It is designed to capture one of the servo horns and allow a better connection between the servo and the steering.

We have a pole that allows us to reach our attic ladder, and I wanted to create a bracket so I could mount the pole inside a closet. The pole is roughly 31 mm in diameter.

I designed the bracket from scratch using Sketchup.

I added supports to the arms to assist in printing. Once printed, these break away easily.

At long last, everyone in the world (ok everyone who has access to a 3d printer) can have their own bust of America's greatest entertainer and statesman, Stephen Colbert.

Even better, you can use this model and your favorite 3d modeling software to add Mr. Colbert's face to objects which were formerly lacking in Colbert heads, like bannisters, umbrella handles, toothpaste squeezers, and rabbits. (To name a few.)

Made with a Polhemus 3d scanner at the Colbert set on 6/6/2011.

This is recreation of a Roman ballista. Its small (obviously), and isn't an exact replica (Romans didn't work in plastic). Its about the right size to fire a pencil.

It should be fairly obvious how it works, but I have some instructions below, and a short movie.

P.S. I am aware of the Thingiverse policy not to publish "weapons". I see this as a toy -- it can fire a pencil about two feet with considerably less force than I can throw it. However, please be careful as points can always put out eyes. Also I know someone could potentially beef this up until it fires knives at a 100 miles and hour. Please don't.

TODO: this is a work in progress because there's some things I want to add.
-- a mounting point so you can put it on a "table" (a stand on a pedestal).
-- a ratchet, winch and trigger mechanism, that are vaguely period

First attempt at a sink drain screen with a knob that can be turned to close the holes. It's parametric so it can generate any size you need. The parts snap together, but the cap may need a drop of super glue to hold it together. Play with the tolerance variable till the parts slide together well on your printer.

It worked for me, unfortunately it drains very slowly and needs more holes! Even with the blocker removed and the central hole open, it still drains too slowly.

Here is my take on merging the lowrider and the mendel inspired y carriage for the cupcake.

link to bearings:
vxb.com/page/bearings/PROD/3mm/623ZZ10-1

I went with smaller bearings than the Mendel because it allowed me to do everything with M3 screws and it allowed me to drop the height a bit.

This design is shorter than the standard platform by 10mm, I was pushing for more, but the bearings killed the height gains. It does mean that you can gain back about half of the height that you loose by putting in the automatic build platform.

Also, the y rails have been separated to 70mms so hopefully that means that the platform is a bit more stable.

I attached the solidworks file for people who want to play (WARNING - the file is messy and I was bad and made all of my parts in one part file). If you would like any other formats like .igs, .step and the like, just shout.

Should have all of the holes teardropped later today. - Truncated teardrop holes are up, that's a pain.

Update:
The stl files from solidworks would not slice in Rep G, I have no idea why, if you know please tell me.

I reuploaded all of the stl files and tested them in Rep G 19 they seem to work but I will not have a chance to print until Monday.

I have all of the parts, now on to the debug... so you do not have to...

The updated files are in the zip file, I got rid of the first generation of parts. Things were moved around a bit and these are the updates after printing round one and putting it into the makerbot. I should have all of the gen 2 parts printed and through debug tomorrow.

Update 2 - I got the bearings in and other that a few "What the hell was I thinking..." moments that were easily repaired with an X-acto knife, everything went great. I'm in the process of printing the gen 3 parts and everything should be cool now. I'll post pictures and video once the final draft is printed.

Update 3 - In process of using gen 3 platform to print gen 4 platform. Once I have printed and assembled it, I will upload files. I think that will be it for variations.

Update 4 - Gen 5 files are out and I can now say you can download them and print!

Update 5 - Instructions are up.

Update 6 - I just uploaded the gen 7 version - I have not had a chance to print it yet, I was getting annoyed with the slight curve in my heat spreader and decided to rip it apart and lap it until it was flat.

This update addresses:

Adding nut pockets on all adjusting screws for bearing tension to make adjusting easier (do not have to hold nut in place)

Back X bearings cluster has been reworked so the is less interference with the X pulley.

Back X bearing adjustment screw head has been nested into the plastic to have less interference with X belt.

Interference between Y belt attachment nuts and plastic bodies has been addressed

X belt attachment point has been lowered.

First shot at integrating endstops have been added.


I think that that is about it. I will shout when the directions have been updated, everything should be the same except the endstop part.

If you have already printed this and do not want to reprint, reprint parts 09 and 16, those have to do with X belt and pulley issues. (and they are small)

I just sent out the third package of nuts, washers, and screws. If anyone else wants them, just message me.

Gaffertape kindly updated the files so if you are using the older repG and skeinforge, use the resaved gen 7 files.

Update: Finally updated for mechanical endstops, instructions still need to be updated though.

This is a derivitive of "Platform Leveling Trick" by ScribbleJ. thingiverse.com/thing:6545
This version uses stuff that I had lying around the house. It uses springs out of a mechanical pencil (which fit perfectly over the bolts), to make it easier to level the build platform. It might take a little bit of the stress of the extruder nozzle, to prevent it from breaking your extruder, if it is laying down too much plastic also.

Here is the humble mansion, a bit of Americana, the outhouse.

When I mentioned to my significant other that I planned to print robmeyer's urinal (thing:6261) she couldn't quit laughing. Then she suggested that I design an outhouse. So here it is.

A Thingiverse model in block text to print out! Two whole bricks tall for extra thick relief and better perspective legibility!

Do you need a pot to grow some "herbs" or pretty flowers? Then look no further; the MakerPot is the answer for all you container gardening needs.

Included below are .stl files to run through your slicer of choice as well as the native Pro/Engineer files used to create them. There are two sizes of MakerPots to choose from but of you could easily scale any one of them to get your desired size.

The MakerPot come with the stylish MakerBot "M" logo on its rim and is 100mm in diameter and 100mm tall.

The Large Pot is the same size as the MakerPot just without the "M" and a smaller rim height

The Small Pot is 70mm in diameter and 60mm tall and does not have an "M" logo on it.

There are optional corresponding saucers that can be printed that snap into holes on the bottom of the MakerPots.

This is a derivative of thingiverse.com/thing:4458. When I built the shorty version I had trouble getting the parts to print correctly and I wanted the ring to turn further to fully open the box.

When I designed this iris box I started from scratch and used a different mechanism to open the box.

I have also uploaded the NX6 .prt files for anybody who wishes to use them.

[Update] This thing unfortunately was one of the victims of the recent “catastrophic hardware failure” at Thingiverse.com. It used to be "thing:4811", now it's "thing:4812" :)
I'm not sure if it's possible to recover the comments on the original thing (as far as I know, the comments section is outsourced and not part of the thiniverse servers).
Also, the "Likes" are gone... Do you still like this thing?

Since the original frame of my Gaui 330XS Quadrocopter was damaged in a crash, I built a new frame from scratch, using printed plastic parts.
The four arms are 10x10mm wood profiles (cheap, sturdy, light weight). The motors and electronics are cannibalized from the crashed Gaui Quadrocopter. But it should be no problem to use other motors and/or electronics for this.

Beco Blocks are 3d printable, snap together, ball and socket based building blocks.

Initially created as a prototype for another ball and socket based project, these blocks functioned so well I decided to make a number of variations to allow the creation of more complex objects.

Created at Robots and Dinosaurs, the Sydney, Australia hackerspace.

A kinetic sculpture made using my parametric bevel gear script inspired by this: brainblog.to/item/2008/11/herz-aus-zahnraedern
I modeled the entire thing from scratch in OpenSCAD, starting with the Parametric Involute Bevel and Spur Gear script I posted some time ago. I have added an additional complexity to the movement because not only do the gears spin, but the axes of the gears rotate too.

Being a kinetic sculpture, you really need to see it in motion:
youtube.com/watch?v=Zx28cHA4_KI

Be warned that before you attempt to print this, an improved technique for attaching the gears to the central mount is really needed.

I have the openscad files for everything, although there are so many parts that it is a bit of a process generating the STLs from them.

If someone wants to collaborate on a better way to mount the gears, let me know.

Inspired by thingiverse.com/thing:4244 this is a box that opens when you twist the outer rings in opposite directions. See this video by Labmat: flickr.com/photos/matthewlaberge/5101233486/

Edit I: Design has been modified to increase the clearance between moving parts. I've also centered and oriented the parts in better positions for printing.

Edit II: Design files posted. DXF, STEP and the original CATpart for those with access to Catia. Thanks to everyone for your photos, videos and design feedback!

This is a slight improvement on my own Escher Cookie Cutter design. The top is now open so it's easier to get the dough out. I've made a bunch of cookies to prove it works. Good stuff to test the Frostruder on if you ask me....

Not entirely satisfied yet with the mean-ness of my katana, I decided to go to town with a revolver too. Here is an iPhone case you can tuck into your board shorts (front or back is fine) and answer calls with a really nasty look on your face (remember to keep your other hand on the katana umbrella).

Yet another overwhelming silly weapon-wannabe. These banana nunchucks let you bring your favorite carb/proteins to the gym while flexing biceps at your fellow Kickboxercisers.

Please note that these Banana Nunchucks work better with straighter* bananas.

Medical prototype. My kid was in a hospital recently, and they had to put him on an IV. The current practice here is to place a support _Under_ the wrist, tape everything up (for immobilization), and have the IV on top of the wrist. The problems we encountered were:

1. No protection for the top of the wrist where the IV was, causing much anxiety on my part on whether the dude was gonna knock his wrist against anything and dislodge the IV needle, etc (wince!)
2. Total lost of dexterity in the hands due to the support block

This prototype proposes to accomplish the following:

1. immobilization of the wrist from the top instead, secured by velcro bands (currently testing using velcro cable ties)
2. top of the wrist is protected by the Y arms of the brace, while still allowing the palm area to be secured by yet another velcro band
3. Fingers can still move (a lot more than before), without compromising the IV placement
4. A lot faster to deploy (dude had to change his dressings 3 times in five days, and each time I freaked out more than he did :-P )
