Finger Fidget

Short description

Finger Fidget: a 3D-printable fidget toy consisting of an inner and an outer ring. Import both STL files into Cura, centre them together on the print bed and print them at the same time. If the inner ring is too tight, scale it slightly on the X and Y axes and use exactly the same X and Y values for a smoother fit.

Light sanding can make the movement even smoother.
The shape is inspired by bearings and ring structures but without complex parts.
