U1 Extruder Gear DLC Hardened Steel Kit, Injection Molding Handle & Integrated One-Piece POM Reduction Gear,Direct Drive Wearproof Anti-Slip Replacement Parts Works with PLA ABS PETG

Compatible Printer Model: This u1 extruder gear upgrade kit is exclusively designed for Snapmaker U1 3D printers. It directly replaces original factory gear accessories, no extra modification required for quick installation and perfect fit with your extruder.;
Lightweight Plastic Handle: The extruder handle uses integrated injection molded plastic instead of all-metal structure. It lightens the moving assembly weight and cuts mechanical inertia while printing, delivering more stable filament feed, less vibration and far smoother performance during long print runs.; Hardened Steel
Drive Gear: The feeding drive gear is made of hardened steel with hardness up to HRC 63-68, equipped with evenly distributed helical coating teeth. Burr-free smooth tooth surface creates stronger clamping friction on filaments, completely avoids filament slipping, skipping and uneven extrusion, and delivers far longer service life than stock plastic gears.;
Integrated Shaft Structure: Adopts integrated all-in-one shaft forming craft to achieve superior concentricity. It eliminates gear eccentricity and shaking while rotating, ensuring consistent, uniform and steady filament transportation. Paired with wear-resistant POM helical large gear, it also lowers running noise during continuous printing.;
Multi-Filament Compatible: Universally compatible with most mainstream 1.75 mm 3D printing filaments, including PLA, ABS, PETG, flexible TPU, PP, PC and other engineering materials. It maintains stable extrusion
