Stack and Sort Toy

Modeled after popular wood toys such as Melissa and Doug (TM), this is a stack and sort toy that can be printed on a 3D printer (the MakerBot print volume is slightly too small, however, unless you shrink the parts by about 10%). It features a snap-together base (Warning: not yet tested!) and pegs that hopefully flex enough to fit into their holes.

The toy is designed to teach children the association between shapes and numbers (i.e. there are 5 pentagons, 4 squares, etc.)
