Floors, lanes and compartments
The box is a stack of trays. Pick a floor to edit it. A tray holds card lanes with dividers and open compartments, placed freely: in the 3D view, click any wall to add one against it, or select one to add another on any side of it. Card counts and names are examples to replace with your own.
Real-size templates print every piece at actual size. A piece that does not fit on one sheet continues across several, to tape together. Most printers cannot print to the paper's edge, so each sheet keeps a narrow unprinted border with a frame to trim or overlap; set it to 0 only with borderless printing. The first page is a guide to joining the sheets and building the box.
A card stop keeps the cards of a lane that is not full from leaning over. Print it on cardstock of 250 gsm or more. Its height and foot are set in the settings panel, under Dividers.
Print at 100% (actual size), with fit-to-page turned off. The 50 mm ruler at the foot of each sheet lets you check the scale. The divider design is changed in the settings panel.
