I have created the hinged, stackable folding unit trays that were in the Knee Deep in Hexes promo pictures. This is my version of them, they are meant to be small, use minimum material, easily printable, and lightweight. You'll notice the game box still has a lot of empty space left; I'm still waiting for both expansions to come sometime next year, at which point I will add the files I create for those as well. That will replace the last stock storage tray and should fill the Box using my custom storage system. Please leave a Like and any comments. Thank you!
