0.3 mm MK8 Brass nozzle designed for printing narrow lines and parts requiring a higher level of detail. It has an M6 × 1 thread and is intended for 1.75 mm filament.
Its 13 mm geometry is commonly used by conventional MK8 hotends. However, an M6 thread alone does not guarantee compatibility: the overall length, seating geometry and contact point with the heatbreak must also match.
Nominal dimensions
- Outlet diameter: 0.3 mm.
- Filament: 1.75 mm.
- Material: Brass.
- Thread: M6 × 1.
- Overall length: 13 mm.
- Length from tip to thread: 8 mm.
- Hex size: 6 mm.
- Internal passage: 2 mm.
- Contents: 1 nozzle.
Applications of a 0.3 mm nozzle
The 0.3 mm outlet can produce narrower lines than a standard 0.4 mm nozzle. It is useful for small figures, lettering, thin walls and details that a larger outlet may not reproduce with the same definition.
It requires careful flow and first-layer calibration. Its smaller passage can also clog more easily, particularly when using particle-filled filament.
Compatibility
Compatible with MK8 hotends using 13 mm long M6 × 1 nozzles. This geometry is commonly found on many Creality Ender 3, Ender 3 Pro, Ender 3 V2 and CR-10 printers equipped with a conventional MK8 hotend.
It is not universally compatible with every Creality printer. Machines such as the K1, Ender 3 V3, Ender 3 V3 KE or SE, Ender 5 S1 and Ender 7 may use longer, integrated or otherwise different nozzles. Always compare the original nozzle before replacement.
Recommended materials
Brass provides good heat transfer and is suitable for PLA, PETG, ABS, ASA, TPU and other conventional filaments. Carbon fibre, glass fibre, metal, mineral and other abrasive fillers can quickly wear the outlet.
Installation
Follow the hotend manufacturer's replacement procedure. Final tightening is normally performed with the hotend heated so that the nozzle seals against the heatbreak. Hold the heater block securely without damaging the thermistor, heater cartridge or wiring.
After replacement, check the Z height, probe offset and first layer before starting a complete print.
Other available diameters
- 0.4 mm MK8 Brass nozzle: balanced option for general printing.
- 0.5 mm MK8 Brass nozzle: wider lines and increased material output.
