Somewhat disappointing that it won’t work with uniform density. More surprising it needed such massive variation in density and couldn’t just be 3d printed from one material with holes in.
Yeah isn’t this just like those toys with a heavy bottom that always end up standing straight up.
But I guess with polyhedra, the sharp edges and flat faces don't give you the same wiggle room as smooth shapes

That implies the interesting question though, which shape and mass distribution comes closest to, or would maximize relative uniformity?
