Floors, lanes and compartments
The box is a stack of trays. Pick a floor to edit it: each column below is one of its lanes, left to right, holding either cards with dividers or open compartments. 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.
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.
