As per a request, here's another Hello Kitty fidget spinner. This spinner uses (4) 608 skate bearings. This spinner is only about 3-1/2" in diameter overall.
Edit: I uploaded a model that uses 5/16" nuts for weights. I also uploaded a model that only uses 1 bearing.
Edit #2: Thanks to Intrudermax for sending the repaired model.
