Creality Official K2 SE Extruder Kit

【Original Quality】: 100% Creality Official K2 SE extruder kit. Specially designed for 3D printer K2 SE and K2 SE Combo; Ensure smooth feeding of the printer 【Built-in Filament Break Sensor】: The built-in "zero-distance" filament break detection mechanism in the K2 SE extruder accurately identifies feeding interruptions and promptly alerts the user; Shorter distance detection reduces waste of filaments 【Built-in Filament Cutter】: A filament cutter integrated into the K2 SE extruder enables precise filament change; The filament cutter is made of wear-resistant materials, which have a longer lifespan and simpler maintenance 【Dual Gear Feeding】: High-hardness, wear-resistant dual gears ensure durability against repeated feeding and retraction, as well as the abrasive nature of fiber-reinforced filaments, significantly extending the lifespan 【Force Up to 80N】: The gear transmission features a 6.25:1 reduction ratio, providing up to 80N of extrusion force (depending on the filament); Ensure more precise control over feeding and retraction volumes
