Texture is a wonderful thing! These little boxes are as much for tactile fidgeting as they are for storing small things. The sides carry rows of grooves and the cap closure is knurled for extra grippableness.
The two halves also have locating features to keep them aligned when being closed - a ridge and protrusion on one side match indentations on the other.
You might notice that the smallest size of these boxes is a vaguely familiar dimension. It's roughly the same size as the Earplug Box from years ago, which is one that I've found useful for all sorts of things, but occasionally wished could be a little more secure! (and just for good measure, there are two longer sized ones, too)

Filament: eSun Yellow PLA+
Print Description
This is an articulated, print-in-place print, so you'll want to make sure your first layer is nice and neat, and that you don't have any printing issues like stringing or overextrusion that might cause moving parts to bind together!
Print Dimensions
The smallest box occupies 104mm x 24mm on the print bed and is 15mm tall.
The largest one is 188mm x 24mm on the print bed and is 15mm tall.
Supports Needed?
Not at all! Designed for straightforward printing!
Scalability
Like all articulated models this one will be sensitive to scaling both up and down. You might be able to mitigate that to some degree with slicer settings, but this is intended to be a small print!
Print Orientation
The boxes print open and hinge-up, and the lid prints closed-side down, like so:
