Feature:1. [Compatible Models] These 3D printer nozzles can be seamlessly used with for QIDI X Max3, for X Smart3, for X Plus3 printers, enabling users to start printing with ease.2. [Brass Material] Made with pure brass at the tip, these nozzles offer superior durability and resistance, especially when dealing with high abrasion filaments such as carbon fiber, glass, or metal filled filaments.3. [Excellent Thermal Conductivity] Thanks to its brass body, these extruder nozzles ensure superb heat conduction from the heating block to the nozzle, allowing consistent and efficient 3D printing results.4. [Funnel Shape Design] These brass nozzles feature carefully cut and polished funnel shape structure to avoid material accumulation in dead corners, thus minimizing the risk of carbonization and nozzle clogging.5. [Universal Compatibility] Performs exceptionally well with high abrasion materials, no challenge for low abrasion materials like PLA, ABS, or Nylon.Specification:Item Type: 3D Printer Brass NozzleMaterial: BrassThread: M6Specification: 0.4mmFilament Diameter: 1.75mmApplication: for QIDI X Max3, for X Smart3, for X Plus3.Package List:5 x 3D Printer Brass Nozzle
