Note: may not be compatible with very early K1/K1 Max units that use a different nozzle type. If you use these nozzles (https://store.creality.com/products/unicorn-quick-swap-nozzle-kit-for-k1c-ender-3-v3), then this model will work
A 2x1 Gridfinity holder for 4x Creality Unicorn nozzles (K1, K1C, K1 Max, Ender 3 V3/Plus). Tight friction fit but easy to get nozzles out. Should work fine in any filament, version in photo is PLA at 20% infill.
