Battle Line - Board game insert
This is a remix of insert https://cults3d.com/en/3d-model/game/insert-organizer-for-battle-line-fits-sleeved-cards
I increased the height so it sits flush with the top of the box, and made the recesses deeper so the cards sit a bit lower.
I've created 2 versions; a 1 plate print, and a 2 plate print for those with smaller build plates.
Note I haven't printed the 2 plate version, let me know if you do and if it works ok.
