I believe contribution was possible, but there were conditions: your contribution had to be signed over so Sun could license it under the StarOffice as well, and you had to have a Sun developer sponsor/actually commit the feature or patch.

The one I have access to is primarily used to make things that I would otherwise make out of wood. Thinking about what I made, I could have used a drill press and lathe to get roughly the same result; however with the required tooling/bits it would have been overkill for something I was only going to make one of. I use a Cupcake basic. Version 0029 of replicatorg is the last I've got working that makes printable gcode, but I use version 0040 to get the extruder zeroed.

Example: I made a stand for a weather station that could be attached to a window. This is something that could have been hacked together out of wood, however it's just as easy to throw a few cubes together in OpenSCAD, perform some difference operations with cylinders, and hit print. Since ABS breaks down in sunlight, I painted the part.

Example: I made a clip that holds a rolling snap-action switch to a cage trap door so I know if the door is open or shut. A cable is attached between some LEDs and the switch to show current status. The switch was attached using adhesive foam strips, but they kept coming off.

On thingiverse, I am a fan of the blowers, turbines, and bellows designs.
