Spiral fidgets

With the idea for the shapes from Jeff McClain's screw mates I redesigned them from scratch with a little more clearance, different pitch and size. 

You can mix and match the outer and inner shapes for extra fun and satisfaction. You can print at whatever layer height you are comfortable with but i did mine at .12mm I printed these all with no supports and had no issues but i would suggest printing the sphere with brim for extra bed adhesion. For the inner parts i would print at 20% infill and the outer parts at 100% infill They look the best when printed in two different colors.

I will most likely add more shapes in the future
