Anyone Have The Laserox Insert with a Deluxe Box?

I recently acquired the deluxe version in a trade, and fell in love hard. I managed to get my hands on everything else through trades and sales, including a Kickstarter expansions box. But now I have five boxes worth of stuff!

I have been looking at the Laserox insert online, and some custom foam from Etsy to see if we can squeeze this down to two or three, but the Laserox site only shows pictures of the insert inside the Big Box. I can’t tell how the insert might fit in the Deluxe box.

Does anyone have experience with this insert? I am also interested in other recommendations if you have them too!
