I made a custom box insert for Magic The Gathering Game Night because the original insert does not have enough space for sleeved cards. This insert supports single sleeved cards, the source sketchup files are included if you want to make changes. The slot for cards is 30mm wide so measure your cards with sleeves to make sure they will fit
For the token holder, I cut a piece of filament to the proper length and superglued it place to be a handle to pull the tray out so you can place it out on the battlefield
The spindown counters stay in place when the lid is on.
Just print 5 copies of the tray in the colors of your choice, and one copy of the center tray.
