It's a fidget Gear Ring that is actually wearable. I recommend scaling down to 55% for a pinky or ring finger or 65% for a thumb, but that's just for me. you will need to print 6 of the sides, one of the middle and two of the bottoms. Then assemble the little gears on the spikes from the core and using a lighter and a spoon or the side of the lighter, melt the tip of the spike and flatten it so the little gear can't come off. Then the two big gears go on either end. If the calibration isn't perfect and the big gears slip off too easily, heating the middle piece and slightly bending out the walls near the end may help keep it together.
Infill doesn't matter because the pieces are so thin, but I recommend printing with the gear teeth facing upwards, and use support on the middle piece to support the arms.
I printed on AnyCubic Mega S, but whatever you're using make sure you calibrate the bed level and have good bed adhesion or the pieces wont stick.
If you have any suggestions, questions or comments, let me know! Good luck and happy printing!
