Fractured Tetrahedron

The Fractured Tetrahedron puzzle is based on the triakis tetrahedron. The four six-sided vertices of the shape have been made into the rotational axes of the puzzle. Fractured Tetrahedron is a jumbling, but non-shape-shifting puzzle, in a similar manner to my QuadStar, Fracture-10 and Fracture-6 puzzles. Each axis can turn in increments of 60 degrees, but axes become blocked if edge pieces are flipped in the wrong direction. This beautiful puzzle is stable and turns very smoothly. It comes fully assembled and stickered. Have fun!
