3D Printed Fidget Spinners
I got these designs off of a site called http://www.thingiverse.com, where you can design templates and share them with the public, or download someone else’s. If you have a 3D printer, I highly suggest you use this site. I managed to find some designs and press the bearings and/or steel balls into them. Enjoy!
