I created this to take part in the first prusapinters.org contest where you had to design a clothes button. And what are the main use cases of buttons? Holding clothes together and play with them. Therefore I a came up with my idea of combining them with a fidget spinner.

This model was printed at 0.15mm layer height and by using a matt filament. After printing you may need to break the two parts free in order to spin them. Have fun with your toy!
