Upgrade Phaetus DXC Extruder for K1/K1C/K1 Max/K1 SE: Direct Drive Helical Gear Smooth Feeding Extrusion Replacement - Support 1.75mm Filament Ensure Stable Printing 3D Printer Accessories

• Compatible with Crealty K1 series 3d printer seamlessly, No firmware or softtware required. Size: 40.1*23.2*56.6mm/1.58*0.9*2.2in
• Helical gear + U-shaped Wheel Design: the helical dual-drive gear system progressively engages filament through spiral teeth, with multiple teeth simultaneous gripping. This reduces filament weat rate by 60% compared to traditional straight-cut gear and minimizes deformation marks caused by gear engagement
• Dual-Gear precision Engagement: the synchronized dual-gear system double contact area, effectively preventing filament slippage and ensuring continuous stable feeding
• Adaptive pressure rocking Arm it automatically adjusts pressure for filament of varying hardness. This ensures stable pressure output, ideal for multi-material switching and reliable extrusion across different 3d printer material types, such as PLA/ABS/PETG/ASA/PC/PA-CF etc.
• Easy to install and use, positioned close to the extruder to significantly reduce consumables waste during changeovers and runout events, improving efficiency and minimizing mess
