I made this geodesic dome as my first experiment using Autodesk's 3DS Max Design 2011. I was inspired by Buckminster Fuller and his domes. I exported it to .STL and scaled it up in replicator-G to print on the Makerbot ToM with Stepstruder MK6. It took 45 minutes to print. You can see more images at:

I was worried that the top might collapse since there is no support material, but it held up.. The very top is a bit 'messy' and blended in, but it held up just fine. It is nice to see it build in rings getting smaller and smaller as it goes up.

Just build it! Maybe use it to stick toothpicks in and put it on the dinner table as a conversation piece.
