Direct-fit extruder gear for Bambu Lab A1

This CNC-machined assembly replaces the original extruder gear on Bambu Lab A1 and A1 Mini printers. It combines a hardened-steel helical drive gear with a lightweight grey plastic idler handle and an integrated ball bearing. The design targets consistent filament transport and reduced vibration during long prints.

Suits owners of A1 or A1 Mini printers needing

Users who want a single-part replacement instead of a full extruder swap will benefit from the lower cost and quicker downtime. Builders running other printer models or requiring a different filament diameter should look for a compatible alternative.

Hardened-steel helical gear

The drive gear uses high-strength hardened steel treated with a nano-electroplated anti-corrosion coating. Helical tooth geometry and an embossed surface increase meshing friction for uniform feeding across 1.75 mm filaments such as PLA, ABS, PETG, TPU, PP and PC.
