I have this go-pro case that works excellently - it has a bunch of arrangeable dividers that allow you secure ships quite nicely, and it's deep enough to have room for everything but the long range ruler. I got it a lot cheaper at REI (with my discounts/member refunds), but you can find some decent ones at Amazon, including their own Basics line - this one has precut foam, but comes with the cut-outs so you can easily customize it if needed. This one is a cheaper version of the one I have. You can search Amazon for generic hard cases and find a ton that come with or without foam/dividers.
I really like this idea!
It works for table transport too, just have to hold it right
I leave it open and use both sides for organizing tokens, dice, etc. during play, and toss everything back in for quick table changes. Big plus is I can toss it in a backpack with a full squad ready to fly and not have to worry about anything getting crushed, as the one I have has a heavy plastic shell and is almost as durable as a Pelican case.
This is one of those games where you can almost spend as much on 3rd party accessories than on the actual product
