This works for both original Splendor and the Splendor Marvel edition. The card trays are large enough for sleeved cards. They can be removed and used to hold the decks during the game. The jewel / infinity stone trays can also be used during the game.
For regular Splendor, print 3 card trays, 6 jewel trays, the regular token tray and the spacer.
For Splendor Marvel, print 3 card trays, 7 jewel trays, the Marvel token tray and the spacer.
The token tray is the only different component between the two editions. I also have a variant of the spacer that meets up with the lid to potentially protect the end of the box a bit more.
The author marked this model as their own original creation.
