I can't find a Cd for an icosahedron, but a cube's Cd varies quite a bit with it's orientation.

There's probably a Cd out there. Doppler radar domes are of this shape, and someone had to do the load calculations for their towers.
If they just went from scale models, knowing the measured loads observed, plus the frontal area of the dome, the Cd would drop out.
