3D printable bearing

This is a makeable bearing, once printed the rollers will be stuck, free them with a sharp tool of any sort. Be patient as this may take you a couple minutes. You do not need to worry about the rollers coming out as they are locked in place internally. To help the bearing run smoother, I recommend a lubricant such as wd40. Inner ring diameter: 40mm (1.57 Inch) Outer ring diameter: 70mm (2.75 inch) Wall thickness: 5mm (0.19 inch) Thanks.
