It's actually a really cool filament (the white one, not the yellow one)! For this style bearing i was able to finally print some that seemed to be good and slid very smoothly when put on rods, but when put on the actual machine i think they were just a little too tight ID because they created too much friction. I need to go back and tweak my model for that again, but my printer is current down and I've been busy with school.
The hardest part about using the tribo filament is that you either have to adjust your model to avoid over extrusion (like i did) or you) or you need to adjust the filament width in the cura advanced settings (probably a better method) because they don't tell you that the tribo filament is not 2.85mm or whatever like most 3mm filament rolls. It's actually like 3.1mm or something!
