Nozzle kit Creality Unicorn for K1C / Ender-3V3 / K1MAX — 2×0.4 mm, 1×0.6 mm, 1×0.8 mm nozzles with heatbrake

Creality Unicorn nozzle kit for K1C, Ender-3V3 and K1MAX (with upgraded hotend) provides a set of interchangeable nozzles and a heatbrake designed for printers that use the upgraded hotend. The kit includes two 0.4 mm nozzles, one 0.6 mm nozzle and one 0.8 mm nozzle together with an integrated heatbrake, allowing users to change extrusion diameters rapidly to adjust flow, layer height and print speed for common filaments such as PLA, PETG and similar materials. The all-metal integrated design enables quick assembly and disassembly during maintenance or nozzle swaps.

Advantages

The kit’s all-metal integrated construction ensures robust thermal stability and simplifies installation and removal. Multiple nozzle sizes let you balance surface detail and extrusion throughput, with the 0.4 mm nozzles suited to finer detail and the 0.8 mm nozzle for higher material flow. The supplied heatbrake helps maintain a sharp thermal break between hotend and cold zone, reducing filament jams when printing flexible or temperature-sensitive materials. Compatibility with K1C, Ender-3 V3 and Ender-3 V3 Plus (and K1MAX with upgraded hotend) makes this kit a practical choice for users who need flexible extrusion options without modifying the printer’s main hardware.

Suitable for

• Changing nozzle diameter to adjust print detail and speed
• Printing PLA, PETG and other common thermoplastics
• Switching between detailed prints and high-flow functional parts
• Routine maintenance and nozzle replacement on upgraded hotends
• High-speed printing scenarios where increased flow is required

Key specifications

• Nozzle sizes: 0.4 mm ×2, 0.6 mm ×1, 0.8 mm ×1
• Design: all-metal integrated nozzle and heatbrake assembly
• Maximum flow rate: up to 30 mm³/s
• Supported printing speed: up to 600 mm/s (high-speed printing support)
• Compatible filament types: PLA, ABS, PETG, TPU, PP, PC, PLA-CF, PA-CF, PET-CF and similar blends
• Compatibility: designed for printers with upgraded hotend such as K1C, Ender-3 V3, Ender-3 V3 Plus and K1MAX with upgraded hotend

How to use

Power off and cool the hotend fully before starting any nozzle change. Remove the existing nozzle and heatbrake following the printer manufacturer’s instructions or service manual, then install the desired nozzle size from the kit and fit the supplied heatbrake ensuring proper thread engagement and thermal paste or sealing where applicable. After assembly, perform a cold and hot extrusion test, recalibrate nozzle offset and re-level the bed if necessary to account for the new nozzle diameter and adjusted flow. Gradually test print small calibration models to fine-tune extrusion multiplier, temperature and print speed for the selected filament.

Usage recommendations

Use the 0.4 mm nozzles for higher-detail parts and finer layer heights, the 0.6 mm nozzle for a balance of detail and speed, and the 0.8 mm nozzle when higher flow and faster prints are required. For flexible filaments such as TPU or composite filaments, ensure the heatbrake is installed correctly to reduce stringing and jams. When switching to a larger nozzle, increase layer height, line width and flow settings proportionally and run a flow calibration print to verify extrusion consistency.
