Features: Upgrade replacement part kit, this HGX-LITE extruder parts kit is mainly compatible with CR-10, CR-10S, Ender3 V2/Nex, and Ender-5 series models. It supports a wide range of standard diameters of 1.75 mm filaments, including PLA, ABS, PETG, TPU, PP, PC, Nylon, PEEK, PEI, and more. Very well-made parts, compared to the old version, this accessory is more durable and stable. The larger extrusion wheel of the extruder increases the grip of the consumables, reducing slippage, while the larger transmission ratio increases the torque to enhance the thrust force of the extruder. To ensure optimal performance during daily printing, it is recommended to regularly add grease to the gear basket bearing. Any problem, please contact our store without hesitation. Honor to serve you.
