Print-in-place fidget bracelet / bangle

Have fun with this rotating fidget bracelet! It consists of two parts which can rotate freely around each other.

Use the customizer to get different sizes, or install OpenSCAD on your own computer and follow these instructions to customize your ring.

I also uploaded many sizes (inner diameter in mm from 54mm to 83mm, please use the conversion table below in case you are used to your local ring sizes). The STL filenames have the inner diameter in mm in the filename.
 

Thanks go out to aubenc for the knurledFinishLib_v2.
 

If you could take a picture of an actual print, please “add a make” and attach the picture. - I am curious to see your uses in the wild! Please let me also know how you rate the design.

Avoid detaching rings
Thanks go out to user_184205770 to make it easier to create rings which are less prone to detach from each other. Just set ridge_w to 2mm, and the two rings become more chunky but also dont detach so easily.

Print instructions

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.
