Features 1、[Upgraded Dual Gear Extruder] Features full metal design, all parts are precisely machined for guaranteed accuracy. The camo shell is made of anodized aluminum alloy, while the reduction gear is CNC machined with POM material and quenched and electroplated. 2、[18mm Extrusion Wheel] The enlarged extrusion gear design provides increased grip on filament. All gears use precise bearings for high transmitting accuracy and longer lifespan. 3、[Stable Printing Accuracy] The dual gear design with angled teeth along the axial direction offers well friction and guidance for linear filaments, ensuring stable transmitting. This design reduces slippage and offset along the extrusion wheel axes, enhancing 3D printer printing accuracy. 4、[Versatile Compatibility] Compatible with a wide range of materials including PLA, ABS, PETG, TPU, PP, PC, Nylon, PEEK, PEI, and more, suitable for Ender 3 V2, for CR10. 5、[36mm Stepper Motor] Equipped with a high temperature motor featuring a 10 tooth gear and a 1.8 degree step angle. The compact and lightweight design allows for better speed and torsion.
