Prusa MK3 Extruder Idler With Bearing
thingiverse
This mod swaps out one of the Bondtech idler gears with an MR685ZZ bearing, allowing you to do so without altering any other components of the extruder body. Additionally, it necessitates a 5x25mm stainless steel shaft, though printing one could be an option if that's what you prefer. I personally favor the increased rigidity and strength that comes with using steel. **Required Components** * [1 x 5mm Diameter Shaft 25mm Length](https://www.servocity.com/5mm-stainless-steel-precision-shafting#371=464) * [1 x MR685ZZ Radial Bearing](https://www.amazon.com/gp/product/B00GGQ4YJK)
