This spring-loaded gift box closes using an irising mechanism. Perfect for giving gift cards, candy, or other 3D prints to your loved ones around the holidays. I used this model this year to make giving gift cards a bit more fun.

I prefer Printables UI, ability to upload 3mf flies, and rewards program; but I wanted any of you who are on Thingiverse to find it if you want it. Here is the link to the models, description, etc.
