Keep the documented MK8 setup on an earlier Ender-3 model with a matching spare, or use the SE/KE conversion assembly if you intend to change to Creality’s documented quick-swap setup.
Fit guide
Find the nozzle that fits your printer and hotend
Start with the complete printer model and the hotend that is on it now. If you bought the printer used or fitted an upgrade, check the installed assembly against the maker’s replacement diagram. Save that match before comparing nozzle openings or materials.
What to check
- Read the model suffix on the printer or in its information menu. On a Creality Ender-3 V3, the SE and KE suffixes matter when you look up a nozzle.
- Check for a replacement hotend or conversion kit in your order history. A machine name identifies the original platform. A confirmed upgrade can change the nozzle it takes.
- Match the mounting format on the maker’s parts page, then select the opening and filament size. An opening of 0.4 mm can be offered in several incompatible mounting formats.

Compare the two bare Bambu hotends when choosing between an existing 0.4 mm profile and a planned 0.6 mm profile. Neither pictured configuration adds a wired fan or heater.
Questions about this choice
Will a Unicorn kit fit any K1 or K1 Max?
Check whether your K1 or K1 Max has the integrated nozzle that Creality specifies for the kit. The maker also lists a separate high-flow nozzle kit for K1 and K1 Max. Use the installed hotend to decide which listing to open.
What should I check on a secondhand printer?
Look for a previous owner’s hotend upgrade or adapter and confirm its part number or format. If you cannot identify the installed part, take a photo and compare it with the printer maker’s service diagram before ordering.
