Void 6x6x6 is a twisty puzzle, inspired by Katsuhiko Okamoto's famous award-winning Void Cube, a hollow version of Rubik's Cube. This 6x6x6 version introduces a completely new way of turning, in which edges turn into the cube.
YES, THIS PUZZLE IS FOR SALE. Unfortunately, it does not fit within Shapeways' upload limit, so the only way to buy it is from me directly.
