it can be cut free, but then i have to find a way to clamp both ball and cage.

the program works with some loops and parameters, calculating the radius and z-heigt of a given ballradius, and angle, clearing it to a diameter represented by the end-angle, this way, the stepover is constant on the surface of the ball.

The brass looks really nice as well as the actual model, I think it's amazing how precise computers can be o_o

Is the ball totally smooth? I'd imagine you'd have a little burr or protrusion at the point where the ball is finally separated.

fancy sharing the g code

Cool, I've made dice in a cage before, but not balls in a cage. I made a double dice in a cage in school as a programming project. It's a .5" die floating in a 1.25" cage that floats inside a 2" cube. Good conversation peices.

I sent you a clip of our finished caged ball.

Kind of like watching grass grow huh? When done, is the ball completely cut free so it rolls around inside the cage? Can you cut the ball using 3D? Moving XYZ over the surface? Pretty cool!
