Specification Brand : Buachois BulletPoint1 : All Encompassing Compatibility for Well Known 3D Printers:Regardless of whether you possess an Ender -3S1, 3S1Pro, 3S1Plus, or a CR - 10 smart pro, our extruder gear is an ideal match. It's also suitable for Ender - 3V3SE, 5S1, cR - 200B Pro, and CR - M4, spanning a broad range of 3D printers BulletPoint2 : Groundbreaking Integrated Shaft Design:Our gear comes with an integrated shaft design, a substantial improvement over traditional designs. This distinctive structure ensures superior concentricity, minimizing eccentric rotation as much as possible. Consequently, filament feeding becomes far more consistent, and you can anticipate smoother 3D printing procedures BulletPoint3 : Outstanding Longevity with Nano Coated Facade:Featuring an overall hardness (HRC) of 62 - 65 and a facade hardness (HV) of 1000 - 1200, our gear stands out from the competition. Thanks to the nano - coating, it has strengthened toughness, remarkable wear tolerance, and high anti - erosion ability. This implies it can withstand the harshest 3D printing circumstances and last significantly longer than ordinary gears BulletPoint4 : Robust High Strength Die Steel Build:Built from high - strength die - steel, this extruder gear provides excellent load - bearing capabilities. This not only boosts the performance of your 3D printer but also greatly extends the gear's service life. You don't have to be concerned about frequent replacements due to wear and tear, making it a cost - effective option for both hobbyists and professionals BulletPoint5 : Straightforward and Efficient Performance Enhancement:If your 3D printer has been performing poorly due to a worn - out gear, our replacement gear kit is the answer. Consisting of 7 pieces, it's simple to install and can rapidly restore your printer's efficiency. By replacing the old gear with ours, you can boost the overall performance and dependability of your 3D printer, advancing your 3D printing projects to a new level ItemName : Mini Upgrade Nano Coating Gear Extruder,3D Printer Extruder Hardening Steel Drive Gear Parts for Ender 3S1 3S1Pro 3S1Plus,3D Printer Accessory ItemPackageDimensions_Height : 2 centimeters ItemPackageDimensions_Length : 9 centimeters ItemPackageDimensions_Width : 6 centimeters ItemTypeKeyword : 3d-printer-extruders Manufacturer : Buachois ModelName : Buachoisg10nawkeub ModelNumber : Buachoisg10nawkeub NumberOfItems : 1 PartNumber : Buachoisg10nawkeub ProductDescription : Specification: Item Type: Extruder Gears Material: Metal facade Treatment: Nano coating Processing Technology: CNC HV Value: 1000-1200 HRC Value: 62-65 Compatible types: for Ender-3S1/3S1Pro/3S1Plus/ for CR-10 smart pro/ for Ender-3V3SE/5S1/cR-200B Pro and CR-M4 and more
