A unique fidget spinner that has bearings embedded into place. This is achieved by pausing the print between 9.3mm-9.5mm Z height, dropping the 4 bearings in place, then completing the print. The added weight improve the spin, it's easy to print and it works great!

I printed mine at 100% infill with Protopasta stainless steel filled PLA which gave it even more heft and an extra long spin.

The bearing caps can be glued into place with E6000 adhesive.

I like Bones Reds Bearings if you're going for a premium spinner. Or even ceramic bearings.
