Issues that this fixes Miss-aligned Extrusion feed gears Excessive part damage from wear Missing layer extrusion Over and under extrusion Bowden tube failure Filament damage and grinding Jammed nozles Retraction errors Metal fragments enter the hot-end Squeeking and rattling noise Low-quality prints Broken filament Hogging of filament Ender 3 V2 / Ender 3 V2 Neo / Ender 3 Pro / Ender 3 / Ender 3 Neo / Ender 5 Pro / Ender 5 Plus / CR10 S / CR10 V2 / CR10 Max / CR5 Pro / CR5 S CR-3040 Pro Reminder I. for 3d printers with filament detector,as the height of our dual gear extruder may be different from the original one, please print the model to rise up the filament detector to make them at the same height; II. for Vyper users,please calibrate the e-step from 385 to 139 and swap the motor wire sequence to make it turn forward instead of reverse III.for other brand 3d printer users,you may need to print the fan shroud yourself ## Features - 【Dual Gear Extrusion Mechanism】:The filament is gripped by the dual drive much more firmly with less deformation, so it doesn't jam as much in the tube, nozzle or hotend. - 【Upgraded Idler Gear Design】This idler gear is upgraded with two washers on both sides, so the sharp gear will NOT ride against the bottom of the arm or chew it up. - 【Spring Adjustable Extruder】The extrusion spring tension could be adjusted by tighten the screw,which greatly improves the printing accuracy and feeding issue. - 【Application】:This all metal dual drive extruder is compatible with Ender 3 V2,Ender 3 Pro,Ender 3,Ender 3 Neo,Ender 3 V2 Neo,Ender 3 Max Neo,Ender 5 Pro,CR10 S series 3D printer.ONLY suit for 3d printers with motor shaft over 20mm,please measure the shaft length before placing the order. - 【Kindly Reminder】:Please calibrate the E-steps from 100 to 139; Please lubricate the gears before first use;for 3d printers with filament detector,as the height of our dual gear extruder may be different from the original one, please print the model to rise up the filament detector to make them at the same height;for Vyper users,please swap the motor wire sequence to make it turn forward instead of reverse ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.3 out of 5 stars 1,830 Reviews | ## Images ![Redrex Dual Gear Ender 3 Extruder with Two Washers Metal Drive Feeder Upgrade Kit Compatible with Creality Ender 3 V2 Pro,Ender 3 Neo Series,CR10 3D Printer TPU Filament Supported(Motor Shaft>20mm) - Image 1](https://m.media-amazon.com/images/I/71RMLvMrl7L.jpg) ![Redrex Dual Gear Ender 3 Extruder with Two Washers Metal Drive Feeder Upgrade Kit Compatible with Creality Ender 3 V2 Pro,Ender 3 Neo Series,CR10 3D Printer TPU Filament Supported(Motor Shaft>20mm) - Image 2](https://m.media-amazon.com/images/I/719p9P2VIwL.jpg) ![Redrex Dual Gear Ender 3 Extruder with Two Washers Metal Drive Feeder Upgrade Kit Compatible with Creality Ender 3 V2 Pro,Ender 3 Neo Series,CR10 3D Printer TPU Filament Supported(Motor Shaft>20mm) - Image 3](https://m.media-amazon.com/images/I/61AUTKPBhNL.jpg) ![Redrex Dual Gear Ender 3 Extruder with Two Washers Metal Drive Feeder Upgrade Kit Compatible with Creality Ender 3 V2 Pro,Ender 3 Neo Series,CR10 3D Printer TPU Filament Supported(Motor Shaft>20mm) - Image 4](https://m.media-amazon.com/images/I/71lJax5ByhL.jpg) ![Redrex Dual Gear Ender 3 Extruder with Two Washers Metal Drive Feeder Upgrade Kit Compatible with Creality Ender 3 V2 Pro,Ender 3 Neo Series,CR10 3D Printer TPU Filament Supported(Motor Shaft>20mm) - Image 5](https://m.media-amazon.com/images/I/71aqoRUy+GL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: I have a cr10s, do i need right hand or left hand??** A: All the ender 3 and cr10 series need the right version!! **Q: Will this work with anet a8 plus? and what version would i need to buy?** A: You're having trouble with YOUR extruder, too, aren't you? We all are. They're terrible. This will work with your printer if you're fed up with their direct drive and you're converting it to use a Bowden tube. Be aware that Bowden tube extruders come with their own unique struggles, but they're not as nasty as the A8 Plus's direct drive extruders. Since you're doing this conversion, you'll also need some sort of 24V Bowden-style hotend. It mattereth not a whit whether you go with the left-hand or right-hand version for your printer; you'll mount it wherever you figure it'll be convenient. If I were you, I'd mount it somewhere left of center, but your circumstances may be different from mine. While you're at it, you might as well upgrade your linear bearings to polymer, too, and your control board to one of the many alternatives. Whatever you do, don't screw around; replace that power cable NOW before you burn your printer to a crisp! The one that runs from the power supply to the control board. It isn't big enough for that load, and the crimped terminals sometimes catch fire. Replace it with no less than #16 AWG wire. **Q: Will this fit a Monoprice Mini v2?** A: It's designed for the Creality CR-10, but it's a fairly safe bet that it would fit any bowden printer that uses the same size motor for the extruder, and the same size filament (The creality uses a 42-40 stepper motor, but many other stepper motors have the same spacing between screw holes). Depending on the bracket the motor is attached to, it's possible the screws that come with this part might not be long enough, but replacement screws shouldn't be hard to find. **Q: Is this all i need to upgrade an ender 3 to have a metal hotend for printing petg?** A: You don't need an all-metal hotend for petg usually. The one on the ender-3 will work just fine. The limit of a ptfe tube is around 240-250. Petg prints with a hotend at 230-250 usually, just make sure the filament you buy isn't one of the odd ones that might need higher temps. If you're worried replace the ptfe on your ender-3 with high grade stuff like capricorn and look for lower temp petg filaments. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***S on September 10, 2022* ### ⭐⭐⭐⭐⭐ Review *by A***N on July 18, 2023* ### ⭐⭐⭐⭐⭐ Review *by K***S on April 9, 2023* ## Frequently Bought Together - Redrex Dual Gear Ender 3 Extruder with Two Washers Metal Drive Feeder Upgrade Kit Compatible with Creality Ender 3 V2 Pro,Ender 3 Neo Series,CR10 3D Printer TPU Filament Supported(Motor Shaft>20mm) - UniTak3D Ender 3 Direct Drive Upgrade Conversion Bracket for Ender 3 V2,Ender 3 Pro and Voxelab Aquila 3D Printer for B-MG&Dual Gear&Bowden Extruder(NOT for Neo Series,Extruder&Hotend NOT Include) - Official Creality Ender 3 Dual Z-axis Upgrade Kit with Lead Screw, Stepper Motor and Metal Power Supply Holder, Ender 3 pro upgrades for Ender 3/ Ender 3 Pro/Ender 3 V2 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/383526598-redrex-dual-gear-ender-3-extruder-with-two-washers-metal](https://www.desertcart.com.ar/products/383526598-redrex-dual-gear-ender-3-extruder-with-two-washers-metal) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-22*
