There are gazillion different storage boxes designes, but I have one 5L volume from local store / manufacturer and clasp for closing lid broke so I modeled one, it is not 100% perfect but it will do the job.
I am not a CAD professional nor an engineer, just a 3D printing enthusiast.
This model was drawn and designed in SketchUp.
