Feature: 1. Compatible for Creality CR-10 or other i3 12V 3D printer. 2. The remote extrusion of the control arm for wire feeding is more precise. 3. The torque requirement for the extrusion stepping motor is lower, reduces the probability of failure during plugging and refueling. 4. Compatible with more types of consumables, such as flexible TPU. Convenient filament change. With all-metal extrusion mechanism and hot-end kit, your printer has more possibilities. 5. You can choose short-range extrusion or remote extrusion at any time, very simple to disassemble, because it\u0027s a complete suite, and it won\u0027t affect any of the functions of your printer.
