1.5 inch (38.1 mm) Fidget Spinner Ear Gauges

thingiverse

This is a custom ear gauge that doubles as a fidget spinner designed at my friend's request. It employs two stacked 3 x 6 x 2.5mm ball bearings per gauge piece, with the plug pieces fitting snugly inside to create the held section of the spinner. Due to its unweighted edges, it likely won't spin smoothly unless printed in a dense plastic or metal. I created this primarily as a humorous gesture, inspired by internet memes. If you decide to print this and discover optimal FDM settings, feel free to share them in the comments below.
