The box is well designed and printed perfectly using PLA basic (green and cyan). The box was easy to assemble and the tight tolerances make the box feel great to operate. My only caution to others is that the tolerances on the trays are tight enough that you're going to want to be fairly certain about how you want to orient the bottom tray before putting it in. It could probably be removed without damage, but I didn't feel the need to try. The top tray also went in fairly tight at first, but wore enough after that first insertion and removal that it is now secure but not at all hard to remove.
