Dr Strange Visualizer

Based on the Ancient One's Mandala from Dr. Strange. 

Assembly:
I super-glued 2 little 5mm magnets together to make the center shaft that the medium sized piece sits on. This size magnet allows the small piece to rotate but also translate a little which I think makes more interesting motion than if it only rotated.
 

I suggest printing from 0-1.25mm in orange, than changing to black (green below) so that it matches the extruder motor color. If it doesn't snap right onto the motor, a small amount of blue sticky putty helps it stay in place. 
 

I've had this extruder on my mini+ for almost a year now and it has yet to catch or fall off even though it does move around a bit.
