Giant 1m Fidget Spinner with Bearing (no glue or screws 100% PLA)

thingiverse

This is a very large fidget spinner meant to be printed in multiple pieces on a 300 x 300 printer bed. The entire project including the bearing and holder were designed in Fusion 360 and to not require any glue or screws. The main spinner pieces fit together like a simple puzzle, The bearing is a press fit, and the center holder is threaded to screw together. The whole thing is slightly bigger than 1 meter round (1010 mm). This is a very long print and took me around a week and a half of 24/7 printing on my Duplicator 9 3d printer. It took me several days designing it in fusion 360 including time to print test pieces to make sure the tolerance/fit was not too tight or too lose for the parts to fit together on my 3d printer. I got the idea on how a real bearing is supposed to work from thing:3361380 made by edlsmith. The idea for designing a ball cage made a big difference in how easily the plastic bearing spins. This was designed to not require support except for the balls (print 8 of them). See notes below on Cura settings to help print them as round as possible. They will require some light filing/sanding where the support touches them on the bottom. https://www.youtube.com/watch?v=N3H2889pHUE
