I wanted an insert compatible with the inner sleeves from Gamegenic that I usually use for this kind of games, and found none that matched my needs, so I made one quick and easy ! 

Print without supports, but you could add a brim to avoid warping (I didn't print with a brim and got a bit of warping on the longer pieces, as you can probably see on some pictures).

Print 2 card boxes, 1 coin box, 1 keys box, and optionally 1 messenger box (works without it as well).

It fits the base game and the expansion "Out of the Oubliette!", and will probably fit a lot more cards if other expansions come out. The cards boxes can be used in game as well! (inner sleeves are slippery when new, so it keeps the decks nice and tight).

This model has been designed with OnShape, and is available here if you want to modify it !
