About this 3D model

This is an interesting set of gears inspired by an illustration in a \"Manual of Mechanical Movements.\" It has a big wheel with slots that a smaller gear wheel slides in. The .prt files are Unigraphics files. I originally made this during a class at the Solheim Rapid Prototyping Lab @ the University of Washington (Open3DP) This is an entry in the Makerbot contest (http://blog.makezine.com/archive/2010/04/makerbot_giveaway.html)
