Box Designer
Free Box Generator
Design custom laser-cut boxes with GravoLab. Set the length, width, height, material thickness and finger-joint width to generate a real-scale, print-ready layout for your project.
Add an optional finger-jointed lid with adjustable height and clearance, or a wrap-around band. Use the explode slider and the 3D preview to check how every part fits together before you cut.
Need compartments? Turn on dividers and set the number of cells along the length and width, or customize each cell size individually for organizers, trays and storage boxes.
The built-in 2D and 3D previews make it easy to check proportions and joinery before exporting. When your design is ready, download the complete layout as a single, laser-ready SVG file.
