Specification AdditionalPrinterFunctions : print_only Brand : GBA-SZC BulletPoint1 : 1.The upgraded Dual Drive Gears for 1.75 mm filament, Precision custom cnc machined with high precision guarantees that you get the grip you always wanted. BulletPoint2 : 2.The gears are treated with hardened steel and then treated by nickel plating. Greatly improved the durability and reliability of gears. The extruder controls the filament very well. BulletPoint3 : 3.(Hardened steel)It is more durable and durable. The biting teeth are very sharp and not easy to slip.PS:In a long period of use. There may be a drop in color. But this does not affect the sharpness of the gear. BulletPoint4 : 4.Curved teeth beat 0.03mm.Which is closely matched with the shaft and has high concentricity.The driving force is 15KG.All-metal high-temperature printing at 500+℃, compatible with multiple models.Higher stability, wear resistance and service life. BulletPoint5 : 5.Compared with other brand products, our products are smoother and finer, symmetrical tooth shape, tooth tip is thinner, makes it easier to cut into the filaments.The tooth is shorter and closer to the diameter of filaments, so the meshing of filaments is better than other’s. BulletPoint6 : Superior performance: High-density windings for compact current and enhanced torque performance, high-temperature samarium cobalt magnet steel rotor ensures outstanding durability, and excellent meshing effect through precision gear manufacturing delivers strong overall performance BulletPoint7 : Newly upgraded: extremely smooth surfaces, optimised gears for precise meshing, durable PTFE wires, non-demagnetising samarium cobalt magnet rotor with an overall temperature resistance of class H (180°C) Color : MK8 CompatibleDevices : printer CompatibleDevices1 : Laptop CompatibleDevices2 : Smartphone CompatibleDevices3 : Personal Computer CompatibleMaterial : Alloy Steel CompatibleMaterial1 : Thermoplastic Elastomers CompatibleMaterial2 : Thermoplastic Polyurethane CompatibleMaterial3 : Nylon ConnectivityTechnology : Ethernet ExternallyAssignedProductIdentifier : 9306002948038 ExternallyAssignedProductIdentifier1 : 0746957689638 ExternallyAssignedProductIdentifier2 : 746957689638 FinishType : Finish HardwareInterface : usb IncludedComponents : inc ItemName : GBA-SZC Upgrade Hardened Steel Nickel Plated Dual Drive Extruder Kit for Prusa MK2/MK2.5/MK3 - Dual Gear Upgrade (Type 1) ItemPackageDimensions_Height : 9.8044 centimeters ItemPackageDimensions_Length : 0.889 centimeters ItemPackageDimensions_Width : 6.9088 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : 3d-printer-extruders Manufacturer : GBA-SZC Material : Material MediaSizeMaximum : A4 ModelName : Daewon 3D Printer Kit ModelNumber : 1 NumberOfBoxes : 1 NumberOfItems : 1 OperatingSystem : Linux PackageLevel : unit PartNumber : 1 PowerSourceType : PowerSource PrinterOutput : Monochrome PrintMediaType : unknown ProductDescription : Packing list: Nickel Plated Drive Gear (with the locking screw) X 1 Nickel Plated Drive Gear (without locking screw) X 1 Pulley shaft X 1 Pulley bearings X 2 ProductSiteLaunchDate : 2022-12-20T11:33:20.268Z Size : 0.8mm SpecificUsesForProduct : 3D Printer Extruder and Nozzle Cleaning Style : Type 1 SupplierDeclaredDgHzRegulation : not_applicable SupplierDeclaredHasProductIdentifierExemption : 1 UnspscCode : 26111500 WarrantyType : limited warranty
