Fracture-12

Fracture-12 is based on the geometry of the hexagonal dipyramid. Like my earlier puzzles Fracture-10 and Fracture-6, it is a jumbling, but not shape-shifting puzzle. With Fracture-12, I have truncated the shape since the top and bottom vertices would otherwise be quite large. The puzzle has six axes of rotation, each capable of 90 degree turns, but only when the edges around the vertex are pointing in the same direction. Otherwise 180 degree turns must be used. This beautiful puzzle is stable and turns very smoothly. It comes fully assembled and stickered. Have fun!
