First attempt at a fidget spinner. It prints pretty tight with the bearings I have, so you might want to scale it up 0.5-1%. Spin is nice and balanced. Enjoy!
I was surprised there wasn't a nice rounded edge spinner that was public domain. So, I made one as I want to be able to sell these without giving attribution. I figured I'd pass along the design for those seeking a royalty free hand spinner. Feel free to take it and sell it! Tips are welcome of course.
There really isn't much to infill, so you can probably set it to 0 and it would cut out a small bit of time.
