608 Roller Bearing

Edit: 10/15 If you're having problems with the bearing not wanting to spin, bring your horizontal expansion down by -0.1. I noticed when I switched filaments that when the bearing was put together it was harder to spin than the earlier prints with the same file. Just another tip if anyone is having issues with the print.

Edit 10/5: I realized that while the wheels printed fine for me, they may be a bit too close together, so I added an individual wheel. I believe the bearing requires 10 of them to work properly. I hope this makes printing the bearing a bit easier.







I originally wanted to make this because I just bought and Ender 3, didn't own a filament holder, and wasn't sure where to find bearings at the moment. After I scrapped some old fidget spinners I still had the urge to try designing my own roller bearing.

I couldn't find many bearings on thingiverse (but at the time I was looking up ball bearings) so I thought I'd take a crack at it.
