This post includes a “tray” and a “cover.” The idea is that they fit together and look like a little compass. The tray holds the canteen and your resources, and the cover has little notches in it meant to hold the hidden badge and your photos.
I think the cover came out just okay. It was the hardest thing I've ever modeled, and I'm happy with it. Initially I wanted them to attach and flip open somehow, but I also wanted it all small enough to fit in the box.
Print the cover.stl with supports (for the little compass rose icon). The other cover model should probably be extended 2mm.
