This goes along with my fascination of self-hinged support-free items. This heart shaped jewelry box has a unicorn outline cut into the top surface, and a lap-joint to align the halves when they close. The hinge on this is a little looser than it needed to be, because I was running it in in a faster print speed. Little hearts on the hinge face could be a little thicker. Feel free to remix. I uploaded a new version that has small snaps on it for closure.
