Sleeved cards from modules Canine Familiars, Ceremonial Grounds and Ancestors don´t fit the main box (module Aurora Borealis fits, I don´t have any other modules) when all cards are sleeved so I created an insert to fit the box from the Ancestors expansion which can carry all these spare cards. This way when you want to play only the basic game you don´t need to take the small box with you and you can still enjoy the benefits from sleeved cards :-).

All you need is to print files Cards01 2x and Cards2 1x (or Cards2_text). I printed it with 4 walls, without top and bottom shells, 20% honeycomb infill, 0.2 layer height, 0.4 nozzle.
