1 - does anybody know what this puzzle is called ??
2 - besides this one and Alexander's Star are there other puzzles that
use this type of mechanism ??
3 - If anybody uses this mechanism with a triangular faced hexahedron
or icosahedron as the core solid please let me know or any other solid
for that matter.

You left out the most important question:

4 - does anybody know where other people can buy one?
