This design is a heart-shaped display frame and gift box created specifically for standard Instax-style instant photos. The structure allows you to showcase four photographs at once: two placed vertically along the straight sides of the heart, and two placed horizontally following the curved edges. The contrast between straight and curved photos reinforces the heart silhouette and makes the images part of the structure itself.

Beyond being a photo display, the piece also works as a gift box. Once the photos are placed, the interior can be filled with chocolates, jewelry, notes, or additional photos, turning the object into a personal and meaningful Valentine’s gift. The idea is to build an emotional narrative through the images before revealing what’s inside.

The frame is composed of two parts: the base, where the photos are inserted, and a lid that closes the box. The fixation system is cleverly integrated into the photos themselves, which slightly protrude and lock into the lid, keeping everything in place without magnets or additional hardware.

How to Print

The model is printed in two separate parts: the base and the lid. Both are designed for straightforward printing and work best with PLA. A layer height of 0.2 mm and 100% infill are recommended to ensure rigidity and clean edges, especially where the photos slot in. The curved photos need to be gently bent to follow the heart’s shape before insertion. When closing the lid, make sure the curved photos align correctly with the slots; once positioned, a light press is usually enough to lock the box securely.
