I’ve been making my own card storage / sorting solution for Gloomhaven, so I’ll post the relevant files here. So far I’ve done my mini cards; I’ll do the regular cards next.
Mini Cards
3D print files for card trays:
14cm long (holds all Monster decks, sleeved, with card dividers)
Card dividers:
Cricut file – opens with Cricut Design Space(I used 300GSM pearlised cardstock with the posterboard setting)
