Yu-Gi-Oh playing card box it can fit sleeved cards (Titan shield sleeves shown in the picture which are usually wider than most card sleeves used for Yu-Gi-Oh), thanks to the spring/separator it can fit from a 40-card main deck and a 10-card extra deck to a 60-card main deck and 15-card extra deck while holding the cards still. The model I printed has 0.32 mm layer height, 3 perimeters, and 25% infill. The print has 0 top and bottom layers with a honeycomb infill, which can reduce the print time (I also think it makes the model look better), it also has “fuzzy skin” which gives the model its texture (the model I printed also makes less noise when the Lid is opened compared to non-fuzzy skin)
I used 3 raft layers to print the spring as it has a low surface area when printed vertically.
