I designed this heart-shaped box with inspiration from Japanese origami. The lid opens through a folding motion, similar to how origami unfolds. Both the box and the lid are decorated with traditional Japanese-style patterns.

Assembly:
To assemble the hinge, insert a short piece of standard 1.75 mm filament through the hinge channel. You can add a small drop of super glue to the end if you want to make it permanent, but this is usually not necessary. As long as the filament is trimmed flush and does not stick out, it stays in place well during normal use.

It is best to insert the filament while the parts are still on the build plate, right after printing, as this makes alignment much easier. Make sure the left and right lid parts are not mixed up. If they are swapped, the folding mechanism will not work.

Enjoy the use :)
