An openable heart shaped box. This box has hinges in the back that allow the box to open up to 90 degrees. There are four parts to print and assemble:

Closed Heart Box Base

Closed Heart Box Top

Heart Shaped Pin (2x)

Heart Shaped Pin Cap(2x)

When the base and top of the heart box hinges are aligned together, push the printed pin through the holes. After the pin is through, push the cap onto the open end and it will snap on.

If preferred, the pin can be replaced by a M3 screw with at least 30mm length and nut for a stronger pin mechanism.

No supports are needed to print the parts. Recommend PETG if putting unwrapped food inside. If not, any other material is fine.
