Sphere Holder

A display stand for a sphere: polished stone, a baseball, a basketball, or a marble. The seat is a cone cut into a square base, so it cradles the ball along a full circle and tolerates one that isn't exactly its nominal size. Adjust it below and download it as STL for printing or STEP for CAD.
