So, to be honest, I kind of refuse to pay the Feldherr prices. Got me an L-Boxx instead, which is an established, robust toolbox that comes with a wide range of options. Bought a bunch of cut-it-yourself styrofoam inserts. Seems to work really well. The box was a little expensive at like 50-something euros, but the foam inserts are like 15 bucks for one set of six layers. Just cut away the bottom one, there should be more than enough space above this one for the squads. Seems to work really well.
