A 100 × 70 × 50 mm inside box in 3 mm plywood becomes a 106 × 76 × 56 mm outside box with 9 mm fingers; the six panels fit on about a 325 × 135 mm sheet (400 mm wide layout) and the total cut length is about 2.5 m.Open the Laser Cut Box Generator

What is the Laser Cut Box Generator?
Enter the inside or outside size of your box, the thickness of the plywood, MDF or acrylic, and a finger width, and the generator produces the six panels (or five for an open tray) with finger joints on every edge, laid out on a sheet and ready to export as SVG or DXF at true millimetre scale. The joints are generated with a rule that gives every corner cube to exactly one panel, so the panels interlock without gaps or overlaps — verified by testing the assembled box in 3D.
A kerf setting makes the slots slightly narrower to compensate for the width of the laser beam, so the fingers press-fit snugly; panel names can be engraved on a separate layer. A second tab creates a living-hinge panel — a rectangle with staggered slits that lets plywood or MDF bend around curves, ideal for curved walls, lids and lampshades. Use the output directly in LightBurn, LaserGRBL, Inkscape or any CAD/CAM.

Questions people ask
How do the finger joints work?
Each panel is a full-size rectangle with notches; a ranking decides which panel keeps each corner so panels never collide.
What is kerf?
The width of material the laser burns away (about 0.1–0.2 mm). It shrinks parts and widens slots.
Can I make a hinged lid?
Use the living-hinge panel for a curved lid or add hinges after cutting.
Is it private?
Yes — generated in your browser.
