Print-in-place discrete fidget ring - Mark II

Have fun with this Mark II discrete (as in discontinuous) fidget ring! If you like the standard fidget ring, the dual fidget ring, but would like to have something more functional, this is it. The internal structure of the ring makes it stop only in 16 directions, showing a specific number from 1-8 through both windows (both on the upper and on the lower half of the ring, so they are easy to find).

In this crosssection you see that all numbers are available twice, on opposite sides of the ring. This way, the holes in the ring will show always the same number.

So you can use the ring to generate random numbers or as a replacement for a 12-sided dice. Also it feels quite different to spin and creates a little rattling noise when spinning.

In case you want to customize things, please install OpenSCAD on your own computer and follow these instructions to customize your ring.

Thanks go out to ixpatch for the idea to create a “dice ring”. He has great print-in-place designs to explore! Thanks also go 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.

And see the “promotion video” of the other three fidget rings ;-)

Unfortunately, the uber fidget ring was deleted due to a design claim, so its no longer available.
