This little box with hinged lid is very sturdy. Printed with Creality PETG-CF (carbon fiber) for the container, and Creality transparent PETG for the lid. It is large enough to fit a deck of cards (see photos) and is super rugged. I love the carbon fiber look, and the transparent(ish) lid works well. I was skeptical about using a piece of filament for the hinge, but it actually works great for this. I printed this flat, and used supports for the hinges. I was worried that this might make the hole for the hinges difficult to slide filament into, but it turned out fine. NOTE: If you resize the box, you'll have to use something other than a filament piece for the hinge.
