Polygon construction kit

thingiverse

This is a polygon/solid construction kit. It can be used to create the Platonic Solids, or other wonderful 3D shapes. This gives kids a great hands on experience with solids and how various shapes fit together. It's a classic mathematics manipulative. My set comes with four sizes--a triangle, a square, a pentagon and a hexagon. They get bigger as you add sides, of course, with the hexagon being very large. I've included a few pictures of simple constructions I made with the limited set I printed out.
