Here's my attempt at a Christmas Ornament in the shape of a Makerbot. This was pretty fun to make, but came out smaller than I thought due to a conversion issue in Rhino. Good thing I'm not plotting a course to Mars...

The large version is just under 3cm wide. The small one is scaled by 75%.

This ornament obeys the three laws of robotics.
