1、Durability: Equipped with a longer extruder motor connection cable, easy to assemble. Applicable for ENDER3 series, including for ENDER3/3S/3X/PRO/V2. 2、Better Performance: Supports all filaments with a diameter of 1.75mm on the market, making the extrusion more precise and smoother. 3、Adjustable Tension: The thumbscrew tensioner allows users to fine tune the pressure exerted on the filament by the drive gear. It is equipped with a 42‑40 stepper motor. 4、Stable Feeding: The direct extrusion structure reduces the torsion requirement of the stepper motor and reduces the possibility of nozzle clogging when the filament is retracted. 5、Upgraded Design: Perfectly suitable for PLA, optimizing the remote printing performance of flexible wires such as TPU. The direct extruder kit is made of aluminum alloy and plastic, durable and wear‑resistant.
