Feature(may vary by option.)

●Double Gear Extrusion Mechanism: The filament is held more firmly by the dual drive, and has less deformation, so it will not clog with the tube, nozzle, or hot end
●【Upgrade Idler Gear】This idler gear has 2 washers on each side and is upgraded to prevent sharp gear from riding up or chewing into the bottom of the arm
●【Easy to Assemble】The set comes with the screws and other accessories you need, so you dont need to buy it separately. Just remove the original extruder aluminum block and screw and you can install the new one. Easy to install
●【Pro Extruder Kit】The package comes with all the screws and gears that you need to replace from the old part, making it very easy to install. The metal construction is sturdy and has been greatly upgraded to the cheap plastic parts that come with most printers
●[Improved Performance] The kit comes with an adjustable bolt so you can adjust the pressure of the extruder gear as needed. The feed hole has a slight chamfer, which directs the filament directly inside to make the feed smooth. Improve the efficiency of your 3D printer
