Quick-Swap Nozzle Kit for K1C/Ender-3 V3/Ender-3 V3 Plus
$9.99
Product Features
- Tool-free quick-swap — all-metal one-piece nozzle and heat-break design drops in and out in seconds, no separate heat-break to thread.
- High-flow performance — up to 30mm³/s flow at print speeds up to 600mm/s, built to keep pace with fast printers instead of bottlenecking them.
- Hardened steel tip (SKD11, Moh's 7.8) — sixfold the wear life of brass, so abrasive filaments like carbon-fiber blends won't chew through the bore.
- Copper alloy heat break — 330 W/m·K thermal conductivity keeps heat even across the melt zone, reducing under-extrusion.
- Precision-machined 0.4mm bore — inner wall roughness Ra<0.4 with no burrs at the opening, for smooth feeding and fewer clogs.

Quick-Swap Nozzle Kit for K1C/Ender-3 V3/Ender-3 V3 Plus
$9.99
Drop It In, Print in Seconds
The nozzle and heat-break come as one all-metal piece, so there's no separate heat-break to thread on before you install it. Unscrew the old one, thread this in, and you're back to printing.
Materials Built to Outlast Brass
A titanium alloy shaft, a copper alloy heat break, and a hardened steel tip each do a different job — insulating, conducting, and resisting wear — instead of asking one soft brass part to do all three.
Precision You Can Feel
Tight-fit joints keep filament from leaking mid-print, and a burr-free opening with inner wall roughness under Ra 0.4 keeps material feeding smoothly instead of catching and clogging.
Fits the Printers You Already Own
One 0.4mm hardened steel nozzle, sized to match the stock nozzle on K1, K1 Max, K1C, K1 SE, Ender-3 V3, and Ender-3 V3 Plus — no adapter, no guesswork.
How to Use
Match the bore to your printer's stock nozzle, swap it in, and you're back to printing — no separate heat-break to thread.

FAQ
1. What size bore does this nozzle have?
A: A fixed 0.4mm bore, etched right on the nozzle, matched to the stock nozzle size on K1C, Ender-3 V3, and Ender-3 V3 Plus.
2. How many nozzles come in this listing?
A: One nozzle per order.
3. Will this work with my K1 or K1 Max?
A: Yes — it's compatible with the integrated-nozzle versions of K1 and K1 Max, along with K1C, K1 SE, Ender-3 V3, and Ender-3 V3 Plus.
4. How is this different from a stock brass nozzle?
A: The hardened steel tip (SKD11, Moh's 7.8) lasts roughly six times as long as brass under abrasive filament, and the copper alloy heat break conducts heat evenly (330 W/m·K) instead of bottlenecking flow.
