Corbeau cases'n crates

I had to decorate some of my buildings with immersive items such as war crates. I found one that fit my needs but it was a unique model and I had to made size variations to avoid a strange regularity in my tabletop which lead to the feeling it is the same model obviously printed 20 times (indeed).
I also wanted that all the crates share some kind of semblance like coming from the same army.
So here are my three crates. I choose a solid fat crate as base to reflect that I don't believe in wooden crates in a 40k battlefield. The bottom is flatten to fit every ground and I redesigned them to allow no-support at all printing.
