Okay, there's a lot of inserts out there for tiny epic galaxies and it's expansion, beyond the black. What I couldn't find was one that also fit the two mini expansions that came with the deluxe edition: drones and satellites & super-weapons. This insert just barely manages to fit the drones expansion in with beyond the black, satellites & super-weapons is an easier fit.

This tray works for both boxes, so use the double print plate if you're using it for the deluxe edition. It'll work just as well for the base game, though you'll have to get creative and put the drone tokens in with the dice if you want to fit both mini expansions in with just the base game.

Obviously, these aren't big boxes, so you might have to jiggle things a bit to make room for the larger boards to settle down into place. In retrospect, might have worked better to add a tray on top of the circular cards for the drone tokens, there's still a bit of vertical space there.
