This is an example output file from a more generic "coin" package I'm working on in OpenSCAD. The Fuse Factory is an art and technology initiative in Columbus, Ohio (http://thefusefactory.org/). This coin is the Fuse Factory logo rendered in an easy-to-print form for demos and such (like the up-coming Ignition 3.0 - thefusefactory.org/2010/01/25/ignition3/)

The "F" in the logo really is rendered the right-way around in the real shape - there is apparently a known POV left-hand/right-hand issue with STL rendering on Thingiverse.

This is the output of an OpenSCAD script that generates a case for the prototype Makerbot Watch (http://www.thingiverse.com/thing:1254)

I was one of the lucky ones quick enough to get a prototype Makerbot Watch, and after assembling and programming it, I never have managed to get a case lasercut for it. I patterned the overall design around the multi-layer wristwatch/pocket watch design included with the Watch entry, but did this one parametrically so I could fiddle with various design aspects.

This is an OpenSCAD script to generate shapes for NEMA rack rails based on user input. It was created with 3D printing in mind, but should be usable with CNC.

I have a number of small (1U-3U), light-weight rack-mount devices but wanted to be able to mount them in more convenient places than a standard rack. These rails could be fastened to the underside of a shelf (by selecting a top cap and top hole) or as the corners for a table-top enclosure. Longer rails (6U+) might be larger than most 3D printers can presently handle, but could be machined out out bar stock or perhaps well-aligned angle bracket on a CNC.

This is a modified OpenSCAD source file that extrudes the original Parametric Vertex Bracket but does not subtract out the two M3 and one M8 holes in the middle of the object. This part prints faster and uses slightly less material. I created it to reduce the total print time on slower Repstraps. The time savings isn't as significant on faster 3D printers.
