Behold the Fidget Ball, a mildly ridiculous six-sided fidget spinner. It holds six individual bearings to let each side spin freely, giving your fingers something to do no matter what angle you hold it in. The end result is a nicely and evenly weighted ball that feels almost slippery as you roll it in your hand.

The ball measures 60mm across and fits comfortably in the hand (my hand at least), it requires no glue or hardware beyond the bearings, and it even comes with a simple stand to keep it from rolling away. It's also designed specifically to make the bearings easy to remove (see last pic) in case you ever want to reuse or replace them. NOTE: The internal pegs are a tight fit by design, to keep the spinning side pieces from ending up lopsided. They'll take some force to press in, but be sure they're firmly seated or the ball won't snap together.

Supports are needed for the larger pieces, but not for the internal pegs or rings. Most of the parts in the photos were printed with .2mm layers, but the side pieces ("top.stl") were printed with BambuStudio's "adaptive layers" feature (this isn't strictly necessary for the spinner to function, but it does make for a much cleaner look). I also strongly recommend printing the pegs with the long flat side down, partly to make printing easier, but also for structural support and to make assembly a bit easier as well.

Six 608 bearings will be needed (I used 608RS, but any 608 should work fine).
