I didn't like how the boxes the cards came with kept breaking when traveling, so I designed this. The box takes a little force to close when you initially print it, but after that, the cards should fit in the box well. I also based the sizing on a normal deck of bicycle cards, so it should work with most card decks. The line through the American flag was caused by the way I printed the case, so it shouldn't happen to everyone's prints. I printed it out in 10% infill as the box doesn't really need to withstand much force. I also printed the box standing upright. Unfortunately, you need a support structure for the flag, but other than that, the print should turn out perfectly. If you like this design, please give it a like and comment on the design. I also have other designs, so if you like this one, consider looking at my other designs.
