A little gimmick for your christmas tree. The model is hollow and has a small hole at the top so you can mount it on the top of your fir tree or pull a hook it the hole to hang it on a branch (or anywhere else).
The model is too small? Just scale it up to your desired size.
If you want some other wall thicknesses just ask and we provide it :-)
Be warned, that this one-piece model is tricky to print!
For the math nerds: this christmas star is based on an harmonic johnson polyhedra (and also exactly modeled) - in detail it is a 20-sided polyhedra (icosahedron) with 20 tetrahedron bodies, each fitted on the right triangle surface of the icosahedron.
