【Complete Replacement Kit】Specially designed for Anycubic Kobra S1 & Kobra S1 Combo 3D printers. This all-in-one kit includes 4 assembled hotends, 4 brass nozzles (0.2mm + 0.4mm×2 + 0.6mm), 25 cleaning needles (0.2mm×10 + 0.4mm×10 + 0.6mm×5), 2 wrenches, 4 silicone socks, and 1 tweezer—everything you need in a single package. 【High-Temp Resistance】Built with a full-metal structure for excellent heat resistance.

Supports high-temperature printing up to 300°C, delivering better results with advanced filaments such as PLA, ABS, PETG, TPU, PP, and PC. 【Anti-Clog Design】Seamless connection between the nozzle and heat block speeds up heat dissipation and prevents clogs. The smoothly polished interior reduces airflow resistance and ensures consistent, jam-free filament flow.

【High-Speed Printing】Features an all-metal throat tube for even heating and smooth filament feeding. Supports print speeds up to 600mm/s without leaks or blockages, ensuring stable and uniform extrusion. 【Plug & Play Installation】Pre-assembled with heater cartridge, thermistor, silicone sock, and nozzle for quick replacement.

Simply remove the old hotend and install the new one. Note: We recommend re-calibrating the heated bed after installation for optimal print quality.
