About this 3D model

Breathe new life into old toys with this gear train! The dovetailed rack gears are male, female, and male/female. The design is a bit chunky so that little hands can easily grasp and manipulate this playset. Now available on Shapeways! http://bit.ly/NapVP5 http://www.zheng3.com/2012/06/16/switching-gears/
