Square Open-Top Storage Container

Create a 3D-printable square open-top storage container with smoothly rounded vertical corners and drainage holes. Outer dimensions: 250 mm long, 250 mm wide, and 75 mm tall. Apply a 20 mm fillet radius to all four vertical outer corners and a matching 17.5 mm fillet radius to all four vertical inner corners so the wall thickness remains uniform. Wall thickness is 2.5 mm and the flat bottom base is 3.0 mm thick. Drill five vertical 6 mm diameter circular drainage holes completely through the 3.0 mm flat bottom base: one in the center and one near each of the four inner corners (positioned 30 mm inward from the outer edges). Keep the entire bottom face completely flat for strong bed adhesion, and leave the top completely open with a flat rim. Clean manifold geometry, no overhangs, ready for FDM 3D printing without supports.

Parameters

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
