This is my own solution for a Truncated Sphere D16 with numbers on faces.
Could you find a better solution?
To make a Truncated Sphere, you have first to build a polyhedron with faces at the same distance from the center, and then intersect it with a sphere of the appropriate size (not to small so that most of the faces should touch, not too big so that they do not overlap).
For the numbers to be on the faces, to each face must correspond an opposite face that is parallel.
