Rollaway organizing?
 

Too late for me to worry about, since I don't do much wrenching these days at my age.
But if I were younger, had just bought a rollaway? I'd definitely look here for modular organizing systems.
(Edit) Yeah, a little spendy, but the modular aspect makes for drawer space saving. Clever designing..

Interesting idea - the modular nature is helpful, but I think a standard metal wrench rack takes up a lot less drawer space (and is a lot less expensive).

I use 2 of the standard-type "formed sheet metal" slot-type wrench organizers in my rollaway, one for SAE and one for metric and both fit in one relatively shallow drawer by orienting them metric small-to-large and SAE large-to-small.

Pretty cool.

If you've got a 3d printer you can make those on demand.
