This is an interactive 3D-printed storage model designed specifically for romantic commemorative occasions. Its key highlight lies in the seamless integration of dynamic visuals and portable storage. The front of the box features a heart-shaped cutout design, with a built-in pink grating strip that reveals hidden patterns through a “heart‑fluttering” animation as the drawer is slid open or closed. Paired with the embossed “LOVE 2026.5.20” inscription on the lid, it exudes a strong sense of ceremony. With a pull‑out single‑compartment structure, the interior can easily accommodate thin small items such as sticky notes, photographs, or tiny cards—perfect for discreetly storing cherished mementos while allowing quick access whenever needed. The overall design contains no superfluous parts, making it simple to assemble via 3D printing. The soft white-and-pink color scheme is both gentle and memorable, offering an affordable yet thoughtful way to create a personalized touch of nostalgia.
