170x120x90mm box with a lid, printable on A1 mini. Solid thin walls so it prints faster than honeycomb/hexagon designs without needing more filament. No supports, no assembly, no glue. It's very simple, but it does the job.

Not waterproof. Not for heavy contents. Can delaminate if it experiences shocks.

I use it for sorting electronic components, cables, and USB etc dongles.

Textured plate is fine, nicer finish with smooth plate but no requirement.
