Print in Place Fidget Ring (21 Different Sizes)

thingiverse

This is my print in place fidget ring design. The concave inner ring keeps the convex outer ring in alignment and allows it to spin freely without any assembly need. I have included a section view of this geometry below. If you enjoy the design a like or make would be appreciated.Check out my new Banana Switchblade design hereYou can obtain a commercial license to sell prints of this here.InstructionsEstimate your finger diameter then select the ring with the corresponding inner diameter.The ring prints in place and no assembly is required.I recommend printing with an outer brim.The gap between the two rings is 0.25mm. If this gap is too small for your printer, scale up the outer ring in the x and y direction until the inner and outer ring no longer fuse together.Adding some generic plastic lubricant significantly reduces friction and allows the ring to spin for much longer.
