Improved Fidget Spinners

thingiverse

I've discovered that crafting the cheapest possible fidget spinner without sacrificing quality is achievable, and printed bearings are surprisingly effective. TwoROBOTGUY's designs are the most successful ones I've tried, so I found a reliable ball bearing (still experimenting with this https://www.thingiverse.com/thing:53451 and this https://www.thingiverse.com/thing:2333792), scaled it up as much as possible, and inserted it into the center of his two designs that I use. They spin exceptionally well, and you can apply this to any design by simply posting a link in the comments.
