Fit guide
Choose the hotend for your Anycubic Kobra model
Kobra is a family name. Use the full model label, including S1, 3, 3 V2, or 2 and its suffix, to get to the appropriate part list. The available openings and materials depend on the exact assembly.
What to check
- Use the model selector on the manufacturer’s parts page and verify the part number or model label against your printer.
- Compare the variants offered for that assembly. Anycubic’s current parts table separates the S1, 3 and 3 V2, and 2 Series options even where two assemblies share the same opening.
- If you are looking at a third-party kit, verify the package contents, connector details if applicable, and the part it is intended to replace.

The S1 wired kit and S1 Max Combo quick-release nozzles are different formats. Check the full model label before comparing spares.
Questions about this choice
Where should I start if I have a Kobra S1 Combo?
Anycubic lists the S1 and S1 Combo together for the hotend options on its parts page. Start with the S1 model in the selector, then compare the options it lists for that assembly.
Can I carry the nozzle diameter from my previous Kobra to my new one?
You can use the opening as a preference. Find the correct assembly for the new model first, then check which versions offer the opening and material you want.
