Coin Fidget Spinner with Half Dollars

thingiverse

I designed and printed a fidget spinner using (6) Kennedy half dollars! It's at minimum a $3 investment. These are close to being a little too big, and maybe even a little too heavy. But it can sure spin! The fit usually works pretty well, and I haven't had to glue any coins in but that would be pretty easy if one wasn't staying in. I've tried a few designs for the center section, and in the end I decided a really basic design was best - I had to sand them a little bit and they fit in well without glue, but I designed them so they could meet in the middle and be glued together if necessary. I used a ceramic 608 bearing - here is where I bought mine: https://goo.gl/Zq7kxN .
