Optional: If you also sleeve your mini investigator cards, only up to 3 will fit in Card_tray_with_mini_card_slot.stl. You either want to print 2 or only put up to 3 sleeved cards in the slot, and the others in between a couple decks between the posts. If you do not sleeve your investigator cards, all 5 should fit into the slot.
This was made without explicitly planning for any expansions.
This is my first board game box insert that I drafted up. As much as I really liked the simple card racks from https://www.thingiverse.com/thing:1906534 they did not fit Fantasy Flight Games grey pack card protectors. The largest pieces were also just big enough to not fit on my print bed. So I used Brahm's design design as a model for smaller card racks, then instead of having any space for miniatures or an shudder all mixed up token cup, I made small, segregated token holders to decrease set-up time. As I use an Android app to draw Chaos tokens, the small space on the side that I had left is only used to store the chaos tokens, not any additional bag. There's still a little bit of room if the fabric of a bag isn't too thick.
