My take on the fidget spinner craze. I printed mine with 20% inflil. The holes for the bearings are purposely tight. I used a hammer and slowly tapped them in. Once in they should move at all. The outside caps are optional, the center cap is also tight again use a hammer to gently tap it into place.
Here is a link to the bearings I used, they are from Amazon and work quite well for the price:
Let me know if anything doesn't fit well on your printer and I will try to get a version that will work for you!
