About this 3D model
This trick box has a hidden latch mechanism that will keep it securely closed until you twist a particular section of the lid. The part that twists can be almost anything! This project comes with several topper designs, but you can easily make your own. https://youtu.be/1muiuHjyLlU All credit goes to :3dprinty on thingiverse (https://www.thingiverse.com/3d-printy) I made no changes I only reposted it on here to access more people.
