Thinking about this, I think there's another aspect, as well...
Many folks (myself included) go a bit overboard when we first start buying hardware, investing in Pelican cases, gun cases, etc, and providing copious amounts of padding around the hardware, because of the investment we have in it.
The reality? This stuff is pretty durable, and doesn't need that level of treatment.
I've switched from padded cases that add a lot of bulk and volume to what I'm hauling. Now, I use flannel "socks" my wife sews for me. They're not fancy, but they do the job and provide the cases with
sufficient protection.
A simple case like this one is more than sufficient -- no need for the bulk of a big, fancy case.
The main priority is keeping things where you can find them, but also where they don't take up a lot of room.
As an example, my AMW 54mm nozzles are all in one small box that fits the four of them perfectly. Each is marked with a silver Sharpie as to which case it's for, and each is wrapped in a paper towel, to keep them from banging against each other, and getting chipped. That box then sits inside my range box.
