Hardened Steel Extruder Gear for Bambu Lab P1S & X1C

This Extruder Gear for P1S and X1C is an internal component designed to handle high-performance and abrasive materials. Built from hardened steel and featuring a shaft upgraded to a bearing structure, it ensures higher precision, reliability, and wear resistance. This lets you reliably print carbon fiber and glass fiber filaments without prematurely wearing down the drive teeth. Consistent grip supports more uniform extrusion (usage-dependent). Install this in your Bambu Lab P1S as an upgrade over the stock straight-tooth stainless steel gears, or in your X1C as a replacement for worn factory hardened steel gears, to unlock or maintain high-performance printing.
