Creality Official E·Fit Extruder Dual Drive Feeder with High Torque Stepper 3:1 Gear Ratio Support Bowden&Direct Extrusion Upgrade Kit for Ender 3/Ender 3 V2/Ender 3 Pro/CR 10 3D Printers

【Dual Gear&High Torque】: With the dual drive structure, the filament can be gripped much more firmly with less deformation, so it won’t jam as much in the tube or hotend which allows more reliable and stable feeding.

Adopted 3:1 gear ratio and equipped with high torque, the stepper will have plenty of torque to drive the geared extruder without missing any steps whilst maintaining reliability and driving force.

【Quick Release】: Quick release design not only makes disassembly and installation more efficiently, but also makes it easier and quicker to replace the hotend.

And it supports both push-type and knob-type to replace the filament.

】【Compact&Exquisite】: The compact size and light weight can solve the jitter of the X axis, which suits for direct drive extrusion especially.

Direct drive can provide precise retraction and better printing result.
