Great Dodecahedron as Ornament

thingiverse

Here is a great dodecahedron. When rotated it creates something like an optical illusion. A version with a hanger for use as an ornament is included. The great dodecahedron is properly constructed from 12 pentagons and usually displayed as 36 intersecting triangles; a procedure not compatible with openSCAD. The method used here replaces each face of an icosahedron with 3 isosceles triangles. See the openSCAD code. Instructions The stl files require a raft and external support. On my Replicator they take about 3 hours to print.
