About this 3D model

I designed this tool to help students visualize the relationship between the three sides of a right triangle and their angles and is part of the Learning in a Makerspace chapter of new book "[The Makerspace Workbench](http://shop.oreilly.com/product/0636920028147.do)" from Maker Media!. Each slide is held in place with a 3/4" 4-40 fastener. Enjoy!
