Candy anyone please tell me what part this is? It just fell out of the feeder of my ender 3 v3 KE and I went down this road because all of a sudden my prints were sticking to my nozzle. Please help.
I don’t have the KE but the left side of part almost looks like it goes in between the extruder gears to guide the filament to it as closely as possible, maybe from the toolhead?
