Summary

Parametric polygonal faces to build polyhedrons! I made them in OpenSCAD, and they are very customizeable. I've only printed the triangles and pentagons, but they're super fun to build and play with. I used a constant side length for each shape so any shape will fit with any other shape, so you can make whatever fun polyhedra you want.

Each toothed side has little indents and nubbins that interlock and create a hinge for either face to rotate about. Currently, this feature only works with four teeth on each face in the OpenSCAD file, but this is a work in progress, and I will make the hinge available for any number of teeth.

These shapes could be used in a lesson about various polyhedra for elementary or middle schoolers, and could assist in visualization. And they're quite fun to build!!
