- Engineering: CNC machined premium brass nozzle with superior thermal conductivity and hardness. Polished inner walls and burr-free edges with tolerance under 0.02 mm ensure smooth filament flow and precise layer deposition. - Compatibility: Designed for seamless use with a wide range of Kobra printers, including Kobra 3, Kobra 3 Combo, Kobra S1-Combo, and Kobra S1. Always verify your model for best fit and performance. Kit includes 10 nozzles for long term value. - Filament support: Engineered to handle PLA, ABS, PETG, TPU, and wood-filled filaments. High heat resistance and smooth flow support reliable printing across materials. - Performance: Rounded nozzle tips promote smooth filament feeding and reduce clogs. Flat contact surface minimizes filament leakage, while the 1.75 mm filament input diameter ensures compatibility with standard filaments and enables quick, trouble-free nozzle swaps. - Applications: - Prototyping high-tolerance parts and functional components in a professional workshop or studio. - Printing with PLA, PETG, ABS, TPU and wood-filled filaments for versatile projects. - Upgrading Kobra printers to improve print quality and minimize downtime with durable brass nozzles.
