I bought a new nozzle, but didn't want to use the 0.2-labeled box for the 0.4mm nozzle I was storing. I also wanted to use a box that would work with MarcosOso's gridfinity nozzle holder (https://www.crealitycloud.com/model-detail/k2-plus-unicorn-nozzle-holder-gridfinity-stylehttps://www.crealitycloud.com/model-detail/k2-plus-unicorn-nozzle-holder-gridfinity-style).
This version's lid nicely holds the nozzle, and the lid stays in the box very well. I think the tolerances might be able to be a little tighter, but not sure if I'll tinker with it any more.
