Remixed the model to:
Inner dimensions and capacity calculation are based on the Boulder 80+, which from some googling holds roughly 90 Dragon Shield single sleeved cards comfortably. I've included a hinge test print to make sure everything will work well but there should be plenty of clearance now.
I haven't printed the 75 card version because I really only needed this for a bunch of tokens that go with one of my Commander decks.
The author remixed this model.
Resized inner dimensions to better fit sleeved MTG cards, increased clearance on the hinges, and created a larger version to fit more cards.
