Pi Day is coming!!! And who doesn't love an excuse to eat blueberry pie? Or any pie? Bonus points if you can spout off the actual pi number while eating your pie.

These fidgets make a satisfying click when fitted with a key switch.

There is a single color STL model, and a multicolor 3MF file. Also one with and without keychain holes. Ball chains work great for all my keychain models.

Most key switches fit nice and tight. I recommended Kailh box white 3-pin key switches. They are good quality and very clicky! They are also easily available on Amazon or AliExpress.
