About this 3D model

A friendly looking Makerbot mascot entry. Designed to be both fun to assemble and printable with out any overhangs. I know some overhangs are allowed but I decided to challenge myself to zero. The wheels can stamp little "M"s in dirt, or clay or be rolled on an ink pad. I originally wanted to make a little cat train, hopefully I'll be able to finish it in time to submit it to the contest.
