If you are using sleeves for Splendor cards you will find difficult to fit the full deck in the box. Also you may want to include my other design for this game "Splendor coin holder" https://www.youmagine.com/designs/splendor-coin-holder, there is no space left in the box to include it (and you will need two of this holders for the 6 types of coins).So I decided to go further and create a simple and lightweight storage solution for this game:- Card holders with space enough for the sleeves.- Space to include 2 coin holders of 9 coins each hole to be inserted side-lying (5 players mode) but box cavity allows to use 7-coins version faced up.Intended for PLA (around 28.000 mm of 3mm filamentABS not so easy: thin walls so watch out for adhesion between layers in the ends.
