Cover for the Quantum Storage Systems® brand QUS220 model bin (7 3/8" x 4 1/8" x 3"). This is a size commonly sold at the Menards® store near me. (SKU: 2454064) So far the ones I they stock all have the little holes in the back sides for the lid pivots to go into even though the picture on their web-site does not show them.
I print with PETG. No supports needed.
