bento lunch box 3d model

Minimalist rectangular lunch box with three internal compartments, thick walls, rounded corners, 3D printable design. The box and the lid are two completely separate objects, placed next to each other side by side, not assembled. The lid is flat and simple, shown separately beside the box, both aligned on the same plane for easy 3D printing. No hinges, no clips, no locks, no text, no logos.
