Since I've switched from MK3S+ to MK4 it is very easy to quickly change nozzles.
Before that I rarely switched nozzles because of the hassle (first layer calibrarion with 3 different sheets etc)
Used nozzles sometimes are difficult to identify (size), and due to frequently switching I sometimes forget which nozzle is in the extruder.
Therefore I've made this nozzle holder / size indicator.
Please note that you have to cut M6 thread in the holes!
Have fun with it.
