I went a bit mechanical engineering with my latest 3D project....
Made a gift card holder with a mechanical locking assembly and -- naturally -- had to make it #Fallout based to start
Open the Vault Door and get your prize. Or radiation poisoning. Whatever....
Of course since it's me I've made it modular for the inserts, including ones where you can customize a little bit of text for gifting it to someone.
Also since it's me the design is suited for any number of locking "ornaments" so expect some #Zelda and other stuff soon, too.
Files on Makerworld, of course.
