Printed bearing 608 no balls no assembly - print in place

Printed bearing with no balls or assembly, easy to print with no supports.
I saw another one like this on Thingiverse but the curve was the other way around which made me feel like it would be less stable.

Print Settings

Rafts: No

Supports: No

Infill: 100%

Notes: I would advise to print this in PLA or ABS. 

PETG is too soft and sticky to allow for the bearing to spin properly.
