This was my project a few weeks ago. On Saturday, at a robotics meeting, one of our mentors had bought an Ultimaker 3D Printer and had not yet assembled it. When you get a bunch of geeks and cool project, stuff happens. So, we soon had a 3D printer. I spent the rest of the week in Autodesk Inventor, making a simplified model of our robot to be printed. We sold these prints at our spaghetti night fundraiser, and hope to have a slightly bigger one in our pit at championships.

That's awesome!
Do you mind uploading your CAD file so i could see how simplified it has to be? I was thinking about doing the same with ours.

Plastic models of robots are always such a cool thing...we have ones of some of our old bots, and it's just so cool (even the totally broken 2009 one...)

how simplified it has to be: one "big" chunk.
If it is more then one part file or more then one solid body, it is likely to complex (unless u want something rattling around inside in which case multiple solid bodies is ok).

Cool! I've been trying to get a similar model made on my team's Thing-O-Matic. Did you use the shrinkwrap tool in Inventor or make a new to scale model? If you did use shrinkwrap, what settings did you use?

I did not use shrinkwrap. I made new CAD drawings for the model at 1:1 scale, scaling them down in the ReplicatorG software that runs the printer. I did reuse some sketches and took measurements from the model, but a lot of the information came from photos of the robot.

I'll have a model up shortly at http://www.chiefdelphi.com/media/papers/2670.

Nice work. You should post it on thingiverse.com
I have been wanting to print a miniature model of 222's robot, but I haven't had anyone to CAD up a miniature to print yet.
Have fun with your friends new toy!

The Ultimaker works pretty well. I'm still getting it dialed in. There is a problem with leaking plastic dripping on the product, which has caused print shifting problems. (The extruder barrel to nozzle seal is critical and it's not documented in the build wiki. )
