Stellated polygon christmas ornament

I started with a spherical rhombic triacontahedron (60 sided polygon generated by a division of an icosahedra).  I tried different ways to turn it into an ornament and found a lot of them weren't printable.  I settled on cutting a tetrahedron into each of the 60 faces.  The model is huge - the pictures show a print done at 12.5% (1:8 scale).  The interior is also a hollow sphere.

I hope you like it!
