I don't know specifically what works for enders, but you want some variation of the bondtech dual extruder gear design
Ordered that. I'm 99.9% sure it'll work with mine. If not I can just send it back. My only concern is I'm not sure if it as a have to attach the CR touch that came with my printer, but I'm sure I can figure that out even if it doesn't have a mounting spot. Guess I'll find out in a couple days lol
