I’m looking at something like this for AAA

I have one for AA size and it works really well.

Does anyone know if they make something like that half for AA and half for AAA? I’d like to carry a couple of each size in one case to throw in my bag instead of having multiple cases.

I’m also interested in the plastic ones I see that kind of look like the battery snaps into the case. I’m not sure how else to explain it.
