For what it's worth I have this:
Amazing deals on this Weatherproof 4800 Case X-Lg Black at Harbor Freight. Quality tools & low prices.

I will take a picture of my layout when I get home if I remember.
It fits the
Air 2s,
SC, FW279, 2 batteries for the FW279 and its charger, 4
A2S batteries, a big brick charger that charges 4 DJI batteries at once, the mini brick charger for the
SC, and I made a little cut out for storing cables and stuff.
After I got the foam all where I wanted it I coated the heck out of it with Plastidip. We will see how well it holds up...
