3 Assembly

Each module connects to four others by inserting a point of one module into a pocket of another as in 7. Modules are arranged into rings of three or four edges to build any polyhedron with square or equilateral triangle faces, or a combination of both (cube, icosahedron, snub cube, etc.)
