Simple Fidget Spinner Caps

I've seen many caps that I've personally tried, but have not fit my needs. This is caused by either too small of print size, not fitting properly, or just poor quality. These are printed to fit 8mm bearing holes, and work very well. They can be printed by any printer at a very high quality. I've printed at 75%, but anything 50% and above for infill is just fine. I hope you guys enjoy!
