Minimalistic Sdcard Nozzle holder (Prusa , Creality, ...)

I dont need no 20 nozzle Box, i only have 4 in use 0.25 , 0.4 , 0.6 and hardened. So since i use Octoprint my Scard reader is free,  i can also use it for holding my nozzles. Super minimalistic, its not in the way, and i allways have them ready to use.
