A reuleaux tetrahedron is a near body of constant width. Therefore, it can roll as if it is a sphere, but is clearly not spherical. I modeled a reuleaux tetrahedron to be used as a roller for my feet, since it is optimal for pressure points in the feet. I also included a meissner body STL of the reuleaux triangle, which makes it into a true body of constant width.
