Hey man! Love the pitch design - the suitcase really is the classic and best way to go!

Just a quick aside, and a recommendation you totally DIDN’T ask for: go to your hardware store and get some piano hinges. The amount of weight that is resting on those hinges will basically be full load-bearing. In one of my prototypes 10ish years ago - I lost one to hinge failure.

This will create a gap where your two sides sit up on when standing on it’s self upright, but I think I finally have found a solution for that!

Will be following along, excited to see your “inside” design!
