pattern on the face of like the structure of the atom, so I gave her the name Atomicahedron ...
it is very important to me puzzle, I was going to build it for several years - it is the first mechanism that I came up with!
but I did not have enough experience and knowledge, first I had to build a lot more other puzzles to before make Atomicahedron.
I got the details of half a year ago, but they have been bad quality, and I thought it would don't turn, but it turned out well!
