I was extremely irritated to have gotten the new Yu-Gi-Oh Gold Sarcophagus only to find out that it wasn't wide enough to hold two decks side by side. So I made a replica to Print it large enough to fit two decks with additional card sorting dividers that can alsodouble to conceal the cards as well.

Scale Box up to minimum of 10% to fit cards into it.Recommend printing the two parts to the box support free, don't use Cura Slicer as it may cause defects, recomend using Prusa. May say there are defects, doesn't affect print.will need to turn support on to print the lid, I recommend printing Part 1&2 of the lid as Part two can double as additional card storage.
