Have fun with this fidget ring! I uploaded many sizes (inner diameter in mm from 12.3mm for kids to 24mm for big fingers, please use the conversion table below in case you are used to your local ring sizes and use the closest value in millimeter) and three ring widths ("normal" - as seen in the picture, "thin" and "wide").

Only a few sizes are available as "print profile", you get more sizes and variations via the customizer button above and as STL.

The STL filenames have both the style (normal/thin/wide) and the inner diameter in mm in the filename. For conversion of ring sizes, please use the “Ring size conversion table” at the end of this instructions page.

Thanks go out to aubenc for the knurledFinishLib_v2 and to Betsy Weber for her fotos of the multicolor rings.

Printing

You can print it without any support, and it prints very fast. Standard settings will be fine, like infill of 20%, layer height of .2mm, 2 perimeters.

After printing, turn the ring a few times to make it spin better. 

In case the inner ring does not stick well enough to the build plate, use the STLs in the folder "OnlyIfYouHaveProblems__Big_inner_Ring_for_more_adhesion”. It has a thicker inner ring, but also more area on the build plate.
In the unlikely event that the ring is fused together(e.g. possible when your printer is not calibrated properly and has overextrusion), use an STL from the folder “OnlyIfYouHaveProblems__Ring_with_extra_wide_clearance”. It has not 0.7mm clearance but 1.4mm(!) clearance.
