【Dual Gear Extruder】- Instantly provide improved print quality and reduce filament slipping by firmly grasping the filament between two gear locked together. high extrusion force, ensuring smooth feeding.Manually change the e steps/mm in the Marlin firmware to 139 steps/mm.ONLY suit for 3d printers with motor shaft over 20mm,please measure the shaft length before placing the order.
【Upgraded Extruder】-Upgraded 1: This idler gear is upgraded with washers on both sides to prevent the extruder base from wearing out as quickly (prevents it from no longer lining up with the gears on the stepper motor).Upgrade 2: This idler gear uses black half-threaded screws (to prevent premature wear of the bearings inside the gear) to increase the life of the extruder.
【Metal Bed Leveling Nuts】-Made by high quality aluminum,last much longer than plastic nuts.The torque of these nuts is large, making it easier to fine tune the hot bed.Metal nut is more powerful and will twist more tightly than plastic nuts.【Hot bed Die Spring】-The 3D printer spring made of spring steel is harder, more durable, has a longer service life and can be reused.(4PCS 25mm springs+4PCS 20mm springs) Suitable for different types of 3D printers.
【Teflon Tube】-ID 1.9mm OD 4mm（High Quality）For 1.75mm filament.Material: PTFE,The tight tolerances make sure that the filament is lead directly to the hotend ,The smooth inner space will more effectively reduce the frictional resistance of the filament inside the tube.(Statement:Our product is not Capricornus tube brand,please do not misunderstand.)
