About this 3D model

New design contest. All submissions need to use bearings in some way to enable the printable side of the submission to do something cool/neat/funny/novel. So the last contest that required magnets didn't receive much attention and was poorly timed (ended on a holiday weekend). I'm supplying more time and money for this one so hopefully there will be a bigger turn out. I would like to do more of these contests but will probably lose interest if there are too few entries. Fido, if you are reading this check your email so I can get you the money from the last contest. Thanks to tmophoto ($15) and Bo L. ($50) for helping up the prize money.
