A neat way to store your nozzles.
Should work with most common (small) nozzle sizes, though I have only tested it with Ender 5/ Monoprice Select Mini nozzles.
It can be printed in 1 piece in about 90 min without any supports.

There are 3 versions which are identical except for the writing on the lid.
("Nozzles", "Brass Nozzles", "Steel Nozzles")

...and one added version without the nozzle sizes on the front.

If you find it hard to open the box, try opening and closing it a few times.
