I saw this at a local hacker space. Mike was kind enough to send me his design with the condition that I posted it on Thingiverse.

Thank you, Mike.

Frame holder for the GoPro Hero3 camera. Openings for USB and SD card, both mics, shutter release and WiFi button. Battery is also accessible without putting the camera out of the frame. Easy fix with a flexible catch.

NEW VERSION 2.3:
I had the issue that the catch has broken. Also the WiFi button was often pressed when putting the camera in or out. The new version 2.3 has a stronger catch and a small gap avoiding pressing the button. Have fun...

The plastic parts that came with my i3 frame kit were unusable. And I wasn't able to print Prusa's original SCAD files from github very well. My other printer doesn't do long bridges well so I redesigned these parts to eliminate or at least minimize them.

I was a little concerned about using zip-ties but they seem to work well in holding the X rods and LM8UU bearings. The extruder isn't modified much from the original except for the placement of mounting holes. I ended up moving them around to get a good fit to the X carriage. That led to the J-Head slot mount plate's bolt hole placement being asymmetrical.

The laser cut holes for the Z rods were a bit oversized so I made a pair of supports. The Z rods are 12.5" versus the original 12" to accommodate them. Now that I think about it, I could have just printed the top header piece with a clamp built into it.

The top left X rod support needs to be carved out quite a bit If I intend to use the full volume in the Z axis. The extruder motor will hit it when it's at or near the zero position in the X axis. Maybe I should think about making a smaller extruder.

A PLA cooling fan duct for a Bukobot with a Bukoschnozzle hot end and initial X-carriage version (with plastic printed linear bearing holders rather than the new all metal design). It should work with either a Vanilla/Green or Duo and with either version of the Bukoschnozzle wooden hot-end insulator design.

One of my design goals for this fan was that it had to be unobtrusive and so it mounts up underneath the X carriage between the two steel rods. This does mean that the top of the fan intake is partially obstructed by the rear linear bearing but that seemed a small price to pay.

###Things I changed from the original design by Ahasuerus:
- increase size so that it fits 50mm fan instead of 40mm
- increase size of the center space to allow for the larger Bukoschnozzle heater block (ID now 33mm)
- cut out an area on the topside to allow the duct to clear the x-carriage linear bearing holders
- slightly increase relative aperture of fan outlet by ~20% (to increase air flow)
- rake inwards the outside annulus edge to increase visibility of printed parts underneath
- add a mounting arm to allow fan duct to be attached to the x-carriage using a cable tie
- removed indentation on one side of air funnel from original model

I have uploaded a second (larger) version of the fan duct which has a internal diameter which is 4mm larger (37mm). This gives more clearance between the hot end and the duct or allows you to position the nozzle closer to the center.

You can now buy this case from my Shapeways shop here: shapeways.com/model/997471/iphone-gear-case-for-shapeways.html?li=modelEdit

This is a version of the iPhone Gear Case that I completely designed and drew myself. It is much easier to print than the first case, as well as being stronger and a better fit. The areas beneath the buttons and sliders has been removed to make them easier to use, and a cutout has been made around the headphone port so bigger jacks will fit without having to remove the case. The edges of the case are also tall enough to prevent the screen from touching when placed face down. I added a bevel to the ledges that hold the case onto the phone that makes the case very easy to print without support.

Paste extruder based on the Moineau pump principle.

Should work as a plug-in replacement for a hot plastic extruder in a 3D printer. However, I have NOT used this to actually print anything. I'm just publishing it in case someone else wants to try it out. (I think it's ready for printing a very small pizza without toppings, but beyond that I cannot say.)

Almost everything is parametrized and adjustable from the SCAD file. However, the resulting design should be evaluated to see if it is still sane after adjustment, since not all of the features are automatically calculated. Particularly the flange and driveshaft diameters must be adjusted by hand to match the other measurements.

Note: obviously it is impossible to build an object from material that flows on it's own - the object would not hold it's shape. So in practice the material has to either be pulled into the extruder by a negative pressure (impossible with PLA printed pump parts) or pushed into the extruder by a positive pressure. In either case the motor axle has to be sealed, or it would either relieve the negative pressure or allow the material to flow up and out from the inlet block.

I wanted a quality calibration and demonstration thing for my 3D printer. And there are a lot of calibration things on thingiverse. But most of them are quite abstract and this is really booooring. So I designed something more realistic, something that lets me try different slicer settings and then directly see the results. And of course something I know how it should look like when printed.

I recently bought a hex driver kit from Amazon and wanted to be able to mount it to the wall. This is what I made to accomplish that :).

Based upon the famous walking Strandbeest from Theo Jansen ( strandbeest.com ). This is a modular clip together system that is FDM printer friendly. No support required.

I have curved the links in an organic way such that the shape of the leg section looks ahem "bra" like, hence the name.

After I found the really cool looking Rubber Band Gun from KAZKIN, I soon realized that I must have such a thing. But can't buy one or get the right plans to build it on my own. So I've tried to make my own cool Gun, for the normal "Monday morning office war"
And of course for my son :-))))

My tribute to the wonderful age of sci-fye and modernism during the roaring 20s, it was truly a golden era for futurism and geometry in Architecture.

This is a fully modular snap-fit (no glue required) model of an Airship. It is the vanilla base for a series of absurd mashups that currently includes a Trireme and a Saturn V rocket. Designed for 3D print, it comes in two flavors: solid and shell.

This was an idea I had when fiddling with the balloon car. I spent the day thinking about how to make it instead of going out to buy new balloons, so I haven't actually tested it with a good balloon, but sticking a straw in the inlet and blowing spins it up pretty fast and makes a cool turbo whistle sound.

UPDATE: I actually bought new balloons! 12" "helium-quality" party balloons. They spin the turbine, but they have larger necks so you have to hold the balloon in place and there is some leakage. I'm working on a version 2 with a larger inlet, as well as a larger diameter output shaft.

UPDATE 2: Version 2 is here, and you can see it work! youtu.be/8Q6svYMZowU
It only runs for about 3 seconds, I'm assuming that's because I opened the inlet up? Maybe because I don't want to pop a balloon this late at night again. Sounds cool, though.

But made from scratch

Good way of showing a student the mechanics of how a engine converts back and forth motion to rotation. Was fun designing in my new AlibreCad program. All movments could be simulated and checked for clearance before printing.
It came out exactly as the simulator showed. After assembling and a little sanding of the cylinder it turned very smoothly.

This is a more generic reminder for some physics laws, like Ohm law.

It uses the presentation used in french school books.

Scanned at the Birmingham Museum and Art Gallery. Part of my series "3D Printed Portraiture: Past, Present, and Future," cosmowenman.com/3DPPPPF.html, shown at the MakerBot exhibit at the Consumer Electronics Show in January, 2013.

Albert Einstein sat for sculptor Jacob Epstein in Britain in 1933, while a refugee from Nazi Germany. Epstein described Einstein's "wild hair floating in the wind" and wrote that "his glance contained a mixture of the humane, the humorous, and the profound."

I scanned a cast of Epstein's bronze portrait in August 2012 in the Birmingham Museum and Art Gallery, where it is displayed in a gallery where visitors are encouraged to touch the artwork. I used Autodesk 123D Catch to make the scan. I printed the piece in PLA with a MakerBot Replicator and finished it in bronze with Alternate Reality Patinas.

This is my first attempt at the outright duplication of a sculpture scanned in situ in a museum, and I am pleased with the result. My scan captured the rough volume of the features' broader strokes, though not all their individual contours. More time photographing and better lighting would certainly yield a more faithful model.

This subject may be a bit of a cheat, though; Epstein's loose style is particularly forgiving, and the nearly uniform, dark bronze patina is pretty straightforward to approximate. And, of course, Einstein's iconic face is so memorable and easily recognizable. His spark leaps through any medium.

This is a fully parametric design of a power supply terminal cover to fit the 12V DC power supplies commonly used on many RepRap printers today.

The different thing about this design is that it is secured by screwing down the cover into one of the low voltage terminals (V-) of the supply with a M4x16mm screw.

The advantage of using this screw down approach to secure the cover is that the cover clearances can then be far larger than if using a friction or press fit.

Since there are many different makers of power supplies of this type and all are slightly different - then hopefully this screwdown version should be more likely to fit your supply without modification (if not then you can always modify the parametric openscad source file yourself).
