"numberOfShells": 1,Technical notes: This is really the same .stl file as we used in Day 32, but scaled down and combined with an upside-down copy of the model so that the top face gets repaired/leveled as we did earlier for the bottom face. In the future, it would still be better to just use a fresh Mathematica .stl output of an icosahedron but this was easier today.
