We made this model in Morphi using tori, cones, ellipses and spheres. You may want to adjust (slow down) the printer speed when printing the top of the bishop chess piece, although no support is needed. Print this model or make your own in Morphi. In Morphi, users of all skill levels can make 3D printable objects on the go using touch, without wifi or a mouse.
