A little two-compartment shelf for baking supplies. I decided to cut the bottom open to save a lot of filament.

I use strong double-sided tape to attach it to the inside of a door of a kitchen shelf, but there's also a version with holes so you can hang it on some screws if it fits your setup better :)

The walls are pretty thin, mainly because there's simply no need to have thick walls for the weight put into them.
