Polygon Construction Toys

Triangles and pentagons that snap together.

Includes OpenSCAD source files.

Examples in the photos were printed on a Makerbot Replicator 2. You might need to adjust the size of the snapping nubs if you're using a different printer or material.

Inspired by these things, but incompatible with them:
