Specification： Name: Double Gear MK8 Extruder Item type: CR-10S Extruder Material:Aluminum alloy Color:Red Suitable: For CR-10S , 3. Ender-3, Ender 3pro, Ender 5, Tornado Advantage: 1.This MK-8 dual gear extruder is made by quality all-metal aluminum alloy, with long life use time. 2.Direct drive extruder Metal clamp match to the spring produce super force press the filament smoothly and easily.Double extrusion mechanism let the filament feeding become easy and relax without block in the tube. 3.The original aluminum alloy driver is supplied for CR-10S . It can also be installed for Ender3, Ender 3 v2,Ender 3pro, Ender 5, Tornado .etc.Stable and durable. 4. 4. All-metal aluminum alloy, diy aluminum block, you need to be assembled it by yourself Package Included: 1 x CR-10 Upgraded dual gear extruder kit
💓【Upgraded Dual Extruder】Dual gears and dual pneumatic combined extrusion structure, large extrusion force, enhanced feeding intensity, ensuring smooth feeding. The double gear rotation design locks the filament, which is beneficial to improve printing quality and reduce filament slipping, high-speed extrusion or retraction, better pressure to push the filament into the printer, less easy to lose steps, faster printing speed
💓【Compatibility】Double gear mk8 extruder, perfect for 3D printer CR-10/ CR-10S/ CR-10S / Ender 3 (initial version)/Ender 3 v2/Ender 3 /Ender 5/Tornado, etc. 1.75 mm filament (Set only for 3D printers with motor shafts exceeding 20mm, please measure the shaft length before placing an order.)
💓【Stable and Durable】All metal aluminum alloy, high quality double gear extrusion, compared with ordinary plastic drive, this high aluminum metal filament extruder is stable and durable. The idler gear has been upgraded with a brass washer added between the stainless steel gear and the aluminum housing, so the gear does not collide seriously with the housing, which helps reduce stock extruder wear.
💓【Adjustable Spring】The tension of the extrusion spring can be adjusted by tightening the screw, which greatly improves printing accuracy and paper feeding problems. Strong extrusion end spring enhances feeding strength and ensures stable pushing of filaments into the hot end of the printer. Suitable for most types of filament, such as ABS, PLA, TPU, PTEG etc.
💓【Imported Materials】The 3d printer dual extruder material is made of brand new imported aviation aluminum material and processed by CNC imported from Japan. The kit does not include the stepper motor, motor bracket and instructions, we need to make them ourselves.
