Museum Rush Game Insert

Heres a custom divider I 3D printed. Unfortunately Room 17 ran out of expansion boxes when it came time for me to receive my shipment.
This divider sits above the height of the box, effectively making the box "deeper" when closed. It can hold all miniatures, both the base game and annex, and sleeved cards, all in the base game box with room for current expansions! I simply use a box band to keep it closed. Check it out!
