Here's an example using either a cylinder, a sphere or both to modify the outside of a cube with minkowski.

}}With this you can make some cool looking knobs:
By using the hollowout code from post # 129 you can make some interesting planters or bowls:
Of course you can use custom shapes made with Inkscape but if they are too complex it takes a long time to render, I will be adding another post on this as time allows and I have had time to do some test prints:
