Jings Pyraminx Sphere

I built this to learn more about designing this type of puzzle. This example is printed in ABS, using acetone vaporization. PLA should also work. FDM prints require split parts for precision at the inner side. Use sandpaper on the tracks to remove plastic blobs. Insert a M3 nylock nut into the core, and use normal M3 screws without springs. Lubricate with vaseline for smooth operation. The puzzle runs well.
