3D model description

Easy to print (no supports!) puzzle project that only requires the following non printable parts:

1x M4 nut
1x M4x80 flat head screw
36x Multicoloured 14mm ABS balls like the these (6 of each colour):
72x 3x8mm cylindrical rare earth magnets

The object of the puzzle is to shift the balls in order to switch from having 6 vertical lines of different colours to 6 horizontal rings, and vice versa. Magnets are used to allow the rotors to snap into alignment. It is very important that one checks the orientation of the magnets when they are being inserted so that the rotors attract each other and stick together to form nicely aligned grooves.

This puzzle was inspired by the following projects:

I hope you have as much fun building and solving the puzzle as I had designing it. Don't forget to share your makes!
