Last one of the leather bound TCG deck box series.
This thing is massive and holds four sleeved Keyforge decks and has an extra slit to store key and chain tracker cards.
I've included a separate box that fits in any of the deck slits, so you can opt to carry less decks and still use the free space for tokens or whatever you want.
The spine of the box has a relatively large cavity and it's enough to hold a set of printed Aember/damage/power/shield tokens (found on Thingiverse).
I am yet to design a plug for this compartment, but i've included a small indentation on the inside to glue a small magnet, so the plug is held securely during transportation.
As with my previous leatherbound projects, just print the box and then trace it on a piece of leather, then stitch everything.
The lid and box are held together using 6x2 and 6x1 mm round disk magnets.
Feel free to check my other projects of the series - I have a compact single deck Keyforge box and two MTG specific ones.
