Fidget spinner
This is a fidget spinner that I designed using fusion 360. This spinner uses 608 bearings. This spinner works very well and is also very light thanks to the waffle design. The caps go through the bearing and attach with a simple friction design. This is one of the best spinners that I have found.
Update: I have just attached a spinner with a curved design.
