20 pcs 3D printer nozzle, M7 thread, MK10 0.4 mm brass nozzle for 1.75 mm filament, high-precision extrusion accessories

This series of extrusion nozzles is designed specifically for 3D printers using 1.75 mm filament and the MK10 standard. Each nozzle is machined from pure brass—a material renowned for its consistent thermal conductivity and mechanical strength—with a precisely cut M7 external thread for optimal tightening. The 0.4 mm orifice offers excellent versatility: fine enough for precise details, yet suitable for typical printing speeds (40–60 mm/s). The 20-piece set meets the needs of demanding professionals and hobbyists, particularly in educational workshops, fab labs, or for small-scale industrial production. No special tools are required for assembly or replacement.
