Project Rebox is a Geometry Nodes utility for Blender designed to automatically generate customized storage containers. The system creates corner brackets intended for 3D printing alongside wall panels optimized for laser-cut cardboard. The setup also includes procedurally generated Gridfinity bins and grids, featuring magnetic insert cavities, specialized glue injection points, and stackable configurations. A bundled Python export script automates the process of saving both STL files for 3D printed components and SVG files for laser-cut lines directly from the node tree.
