Ditrigonal Dodecadodecahedron

Here a ditrigonal dodecadodecahedron also called a triambic dodecadodecahedron. Hart's image - http://www.georgehart.com/virtual-polyhedra/vrml/triambic_dodecadodecahedron.wrl - is not easily printed as it contains pentagons where portions of both sides face outwards. I recently constructed a version using only triangles and discovered that the stl file contained 13 pieces (shells). One piece was a great stellated dodecahedron and 12 pieces were simple 3D pentagrams. This means that one can construct a ditrigonal dodecadodecahedron by printing the 13 pieces separately and gluing them together. Stl files are: gr_stellated_dodecahedron.stl four_3D_pentagrams.stl OpenSCAD code is included.
