I had just received this game as a gift, and looking at the current offerings to organize the box I felt that I'd be better off making my own for fun!
There are 3 areas for cards, and 2 dishes for wound and heart bonus tokens. They aren't in the original game, but they're easy to print and they make tracking points and bonuses easier. The expansions also use coins, and this could accommodate them as well. The 2-compartment dish would be good for that.
Two of the trays will hold the original card set, and the third can be used for expansions if desired. The instructions sit on top. I don't use sleeves so I have no idea if those will fit.
Designed for smaller beds like the Prusa Mini.
Any filament will do. I used 0.25mm layers for the base in PolyTerra Charcoal Black PLA, and 0.1mm layers for the walls in Overture Space Grey PLA for smoother curves.
