Polyhedra Starter Kit

This file contains patterns for the base part (black outline) and connector (red outline) for six types of polyhedron, sized for use with medium PG plywood/draftboard. [Polyhedra] They all have sides measuring 2.5" with matching connector spacing, but of course to combine different shapes you’ll need to come up with the proper dihedral angles, as the included connectors won’t work for that. As always, show me what you make!
