I'm figuring out if the box I put my hands on will fit the bigger ships of the Scum faction. I'd be grateful if someone could post the simple measurements (length, width, height) of those two ships.

Did you get a Plano? The Firespray fits into the large square compartments. In fact, you can fit two there. The Hounds Tooth needs one with two if the large compartments, and you must leave out the divider.

And yeah, magnetize the wings of 666

They then can be slid back on and they fit snuggly, no need for magnets. I have 3 HT's and I can fit them in a Plano 3700 no problem.

They can fit into a Plano 3700 without taking the wings off, but they are just barely too big and require that you close the box on the wings which puts a little pressure on them, which I don't like.

Nope, it's similar, but it's not exactly that. I also want to add some sponge for extra security.
