Decided to design my own spinner ring in CAD, figured I'd share it, included is my own personal design and a blank version that can be modified however you want it.

Depending on the ring size, make sure to print it so that at least one layer of supports is printed between the two rings top and bottom, this needs to be scratched out with a knife after it is done to break the outer ring free. (I ended up using 0.15 resolution at 102% print size for this, it makes about a size 10 1/4 ring)

Can be very hard to get turning at first but once it moves it gets easier and easier.
