Planet Cube: a nice price alternative to the Happy Cube with mind boggling effects!

The Planet Cube is a cube of 3,5 x 3,5 cm made in foam of 6 mm thickness. That makes it smaller and thinner than the Happy Cube (4 x 4 cm, foam thickness 8 mm) and less expensive. Although the Planet Cube is smaller, the printable surface is exactly the same (2 x 2 cm).

The Planet Cube puzzle pieces have 6 teeth. In contrary to the Happy Cube, which has only 5 teeth. That makes the intercombinations of the different Planet Cube puzzles somewhat more difficult than those of the Happy Cube family.
