I recently started back playing Magic and decided I should print a deck box. I made the mana symobls, main symbol, and a deck box big enough for a commander deck. The box is made to use 5x1mm magnets to keep the lid on. I would recommend printing in PLA, since its easy. I made a different box by making cutouts of the blank box in tinkercad and then adding a background to the mana symbols I want to use in the same size as the cutout. I then glued it together. I haven't gotten around to painting/finishing it yet, but it printed jsut fine like this.
