Extruder Gear Kit for Snapmaker U1 3D Printer

### Complete Active and Driven Gear Set This kit includes both the active extruder gear and driven gear assembly. Replace both gears in one go to restore full extruder performance. The two gears work together to grip and feed filament reliably. ### Hardened Steel Coating for Durability The gears feature a hardened steel coating with evenly distributed teeth that resist wear from abrasive filaments. Engineered to withstand long term continuous printing without losing grip, extending the service life of your extruder. ### Wear Resistant POM Helical Gear Design The POM helical gear provides smooth, quiet operation while maintaining high wear resistance. The helical tooth profile ensures consistent engagement with the filament path, minimizing slippage and feeding problems. ### Wide Filament Compatibility Supports PLA, ABS, PETG, TPU, PP, PC, and other 1.75mm consumables. The robust gear design handles both standard and flexible materials without compromising feeding reliability. ### Precision Fit OEM Specification Engineered to match exact OEM dimensions for seamless installation inside the extruder unit. No modifications needed. Direct drop-in replacement that restores your extruder to factory performance.
