Box Generator turns a shape, a lid style, and a few dimensions into a ready-to-slice set of STL files — right in your browser. This is the shape-to-shelf walkthrough.
Every box starts as a rectangular or cylindrical body. Set the outer dimensions, then dial in wall and floor thickness.
Open up any wall — north, east, south or west — and fit it with a plate you can slide out and back in.
Five lid styles, each with its own fit. Screw-on lids get heat-set threaded inserts sized to match.
Every part exports as its own STL, already flat on the bed. All units are millimeters.
