13mm Idler Bearing Toothed Cover CR10

thingiverse

Made this cover to go on an 13mm idler bearing the one with the lip to stop the rattling noise some CR10 suffer from. It can go no both the ends the one where you tension the belt and the guide bearing near the stepper motor that is the one that causes all the noise. You will need some sort of spacer as it is wider than the original i used nut with the threads drilled out as you can see in the pictures.There will be some clean up with an exacto knife as printing leaves two small flat stringy bits on the in side of both of the holes. You must make sure the bearings go in tight or they will break. Sometimes a small amount of superglue can take up the gaps.The tensioner bearing will need the two white spacer tubes cutting shorter be careful to keep them the same length and the guide bearing near the stepper motor might need a longer bolt. Used PLA with a slow print speed.
