A simple tray 135 x 95 x 30 mm for organizing loose items. I sized it to fit the shelf of my bathroom wall cabinet for things like nail-clipper or floss.

The walls are designed very thin, only requiring FDM walls to be printed (no infill or 100%, doesn't matter) and be sturdy enough for this purpose, also not requiring too much material/print-time.

No stackable or lid feature in mind, there are other designs already out there for that.
