Extruder Drive Upgrade Bearing

Recommended Posts

Hi all. I have been having issues with the stock extruder for the UM1. The wheel attached opposite to the bolt with teeth machined into it has been worn down. I have been looking for a solution to this on Thingiverse but I have only found upgrades for the spring adjustment part of the extruder driver. Any files you know of that eliminate that flimsy plastic wheel and allow for the use of a bearing directly?
