Made a couple of small tweaks to my prototype: found a better source to create the logo SVG from (the Wyrdhollow rulebook PDF, not some random image found on Google), and made the magnet holes a little bit deeper.

Everything’s held together with magnets, and there are magnets on the side for the removable tray to snap into place. It fits in the deckbox, taking the space of 3-4 decks (less if on its side, I think).

Pretty happy with it!
