Nozzle Identifier for MK4/S printers

I am using more diverse types of filament as well as a wider range of model types and wanted a way to keep track of the details of the currently installed nozzle. I saw some folks using signs but with a lot of combinations that felt unwieldy.

This model attaches above the power supply of the MK4/S. I simply insert the container of the currently installed nozzle into the holder and now at a glance I can see the nozzle size, high flow or not, hardened or not as well as brand. This comes in particularly handy if I haven't used the printer for a bit and don't recall what I left in the extruder.

I print the model in the orientation shown in the photos with organic supports for that top bit. Takes about an hour using PETG on my MK4S and .2 speed preset.
