Bambu Lab Auxiliary Extruder Gear Assembly - X2D

The Bambu Lab Auxiliary Extruder Gear Assembly – X2D is a genuine replacement filament drive assembly for the auxiliary extruder on the Bambu Lab X2D 3D printer.

Installed inside the auxiliary extruder and driven by the extruder motor, the gear assembly grips and feeds filament toward the hotend during printing and retracts it during unloading and filament changes.

The replacement set includes the active drive gear, passive gear, spring, spring plate, bearing, and mounting screw required to service the filament drive mechanism. Replacing worn or damaged gears can help restore consistent filament grip, reliable feeding, and controlled retraction without replacing the complete auxiliary extruder.
