CAM for CNC code for cutting trispokedovetiles (3-spoke dovetailing tiles)

Excellent. Good to see that it all works. I think that the corner radius was a good plan as it makes the design accessible to those with routers but not laser/plasma/water jet cutters (which probably means most of us) but thanks to Peter for the initial idea and doing the bulk of the leg work.

Needleworks - you need to make another 3 or 4 more. People see them sitting on a flat surface and can't help picking up a tile, turning it round, and dropping it back in somewhere else. At least, they do with my Escher reptile-based design, and I can't see why these shouldn't work as well.
