Printable replacements for the LM8UU bearings using the geometry of an Igus. The results are better than expected.

Printed with ABS at 0.1mm of layer thickness and 3 walls. it may be necessary to add a raft if you have problems of adhesion to your heated bed.

I add two files, one of them has 8 mm of internal diameter and the other one has a tolerance of +0.1mm. I also add the Fusion 360 file if you want to change something.
