Do you think your students could make this on a manual lathe? A 3/8 ball in a 5/8 ball in a 7/8 ball in a 1 inch cube all parts freefloating.
I have made a part similar to your dice in a shop class on a cnc machine. It had a different shape for each face of the cube. So you had to program each face . Like you
said it is easier then it looks. You make the part in a mill vice and after you do five sides , on the last side you pinch the center part in the vice by using a piece of shim
so part is supported while cutting .
I also think if you can hold a diameter and a depth on a lathe it is easy to make a make a cube in a cube. It is Quite a bit harder to make a ball in a cube or a ball in a ball.
How would you make your dice if the outside was round? How would you hold it?
