1. This is an advanced upgrade kit compatible with 3D printers. Tested and tested upgrade kits can be installed quickly and easily to improve the percompatible withmance and reliability of the printer.2. The high temperature resistant silicone protective cover helps to improve the temperature stability of the hot end of the heating block. The silicone protective sleeve can also prevent heat from radiating to the printed part, and keeping the heat away from the printed part will increase overload. This is essential compatible with producing high-quality prints.3. Four flat-end press springs improve the rigidity and stability of the printing bed. The horizontal bed is the key to producing high-quality prints. These improved stiffness flat-end springs mean that your bed stays longer on a level surface.4. The metal extruder has greater pressure to push the filament into the printer nozzle, which improves the percompatible withmance of the printer. You can adjust the extruder gear pressure through adjustable bolts as needed5. Easy to install-remove the old plastic extruder and screw in the new metal extruder, then you can printProduct Name: Filter Spring Kit compatible with Extruder Line EliminatorSilicone sleeve size: 23.3 x 23.3 x 23.1mmDestructor filter size: 40 x 30 x 10mmAnti-vibration sheet size: 55 x 55mmExtruder size: 43 x 23mmApplicable models: Suitable compatible with Ender 3 / Ender 3 Pro / Ender 5 / Ender 5 Pro / Ender 5 Plus / CR-10 V2 / CR-10S Pro V2 3D printers.colour:BlackMaterial:ABS+metalPackage Contents:1 x CR-10S all-metal extruder improved version4 x Yellow mold steel spring2 x A4988 DRV8825 stepper motor de-ripening filter filter de-jitter2 x MK7/MK8 silicone sleeve2 x 42 stepper motor shock-absorbing sheet motor shock-proof sheetOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
