: I don't know how big to make the bounding objects.

For a Dodecahedron and Icosahedron I'd take a sphere { 0 1.2577 } and
for
a Octahedron a sphere { 0 1.73 }. The Tetrahedron is tricky.. a box?
Someone quick in math could calculate the difference of the volumes of
the shapes and the smallest box/sphere/whatever they fit in and see
thats the best result.
