1、APPLICABLE MODEL: This extruder kit is suitable for for CR 10, for CR 10S, for Ender 3, for Ender 3 V2 series, can print standard 1.75mm filament such as PLA, ABS, PETG, TPU, PP, PC, Nylon, PEEK, PEI, etc. 2、GOOD PERFORMANCE: Larger nozzle wheel increases the grip of consumables, reduce slip, greater transmission ratio increases torsion, thereby increasing the thrust of the nozzle and improving print quality. 3、HARDENED STEEL: The extruder is made of hardened steel, wear resistant and impact resistant, the locating pin adopts fine grinding process, quenching and hardening, with a hardness of 48‑50 degrees. 4、APPLICABLE MOTOR: This 3D printing extruder can be used with a 1.8° 1.0A 2 phase circular 36mm stepper motor, which has a greater transmission ratio, higher torsion, and high concentricity. 5、EASY INSTALLATION: Equipped with mounting screws, gasket, hex wrenches, handle and spring, this all metal extruder is easy to install and disassemble, making it a good printing accessory. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
