About this 3D model

This board is designed to assist students in exploring plane shape concepts and is part of the Makerspace Education chapter in my new book "[The Makerspace Workbench](http://shop.oreilly.com/product/0636920028147.do)" from Maker Media!. Simply cut out the board using a laser engraver, attach a length of yarn and add short 1/8" wooden pegs. The peg positions can make a: Triangle Square Rectangle Pentagon Hexagon Octagon Decagon and many more!
