I needed a way to store my spare nozzles and wasn't quite happy with the already existing Gridfinity nozzle holders. That's why I designed my own 1x1x4 Gridfinity box which stores 3 nozzles of each type (0.4 mm and 0.6 mm) and has some room in the middle as well, which can be storage for up to 3 other nozzles, used ones or miscellaneous stuff.
I recommend printing it with 0.3 mm layer height and 10-15% infill.
