thingiverse
Repair of extruder feeder. It fixes pressing lever damage problem. Using original thrust lever as a template, I cut it from 3mm steel sheet and ground lever base to precision fit. Tapping M3 thread and using roller tap M4 are required for secure fastening. I attached printed holder directly to lever base with ease. Result is a feeder that outperforms the new one in every way. The steel base provides barfeeder with crucial stiffness, making it more reliable and efficient.
