Three skate ball bearings in a 3D printed frame. They're fun, and you can make them pretty easily. And they can spin pretty quickly for a handheld, printed device.

I believe it's actually four bearings. One in the middle and one for each of the three arms.

Triangular ones seem to be more common, but there are straight versions also https://www.thingiverse.com/thing:1985737
