Christmas Ornaments from Pentagrams

thingiverse

Two Christmas ornaments feature pentagram designs, each constructed by replacing dodecahedron faces. In one case, equilateral triangles fill gaps between pentagrams to form a polyhedron - the small ditrigonal icosidodecahedron or small triambic iconsidodecahedron. Alternatively, slabs of pentagrams create a self-supporting ornament. Both can be printed directly on the build surface; the open design may require some cleanup but is durable.
