I loved LEGO as a kid and still do, so why not create a variation on my previous design to store 3D printer nozzles. 6 storage spots for each size 0.25, 0.4, 0.6, 0.8.
BTW they are stackable with the others.

Note: Tested with PRUSA MK3S/ PRUSA MINI with 0.4 & 0.6 Nozzles & 0.2, 0.25, 0.3 layer heights to ensure correct tolerances.
