I made this to accommodate the volcano nozzle kit I bought for my K1 Max
There are 6 slots for 0.4mm nozzles and one each for 0.2, 0.3, 0.5, 0.6, 0.8 and 1.0 mm nozzles
The hexagonal holes are 7.2mm to accomodate 7mm, but it should work fine with the smaller ones like the stock Creality K1 volcano nozzles (6mm).
The size markings are raised by 0.4mm so you can switch to another color for the last couple layers to make the text pop. This is not absolutely necessary as you can still read them in single-color prints.
The author marked this model as their own original creation.
