Finger-jointed flat-pack box panels — exports laser-ready SVG packed for efficient material use. No signup.

About the Laser Cut Box Generator

Designer Bee's free laser-cut box generator produces finger-jointed flat-pack panels you can assemble without glue. Set length, width, and height; pick a material thickness; tune the finger width; toggle the lid on or off. Export a single SVG with all panels packed for efficient material use, cut lines in red, ready for LightBurn, xTool Creative Space, Glowforge, LaserGRBL, or any laser software — entirely in your browser, no signup.

Frequently Asked Questions

Are the measurements internal or external?

The length, width, and height sliders are the internal dimensions: the usable space inside the finished box. That is what most people care about, since you are usually sizing the box around something you want to fit. The finished box is one material thickness larger on each wall, so the outer footprint is your length and width plus twice the material thickness (for example, a 100mm internal length in 3mm ply gives a roughly 106mm outer length). The assembled preview thumbnail shows that finished outer size.

What does the SVG export contain?

A single flat SVG with all six panels (or five if no lid) packed for efficient material use. Cut lines are red strokes by default; finger joints are sized to your chosen material thickness so panels self-align without glue. Open in LightBurn, xTool Creative Space, LaserGRBL, or Glowforge — most laser software treats different colors as different operations.

What material thickness should I use?

3mm plywood or MDF is the sweet spot for a sturdy, friction-fit box on most diode and CO2 lasers. The finger-joint geometry is computed from the thickness slider, so set it to the actual measured thickness of your sheet (often 2.7mm for nominal 3mm ply) — accuracy matters more than the round number.

Do the panels need glue?

Friction alone holds the box together for assembly and dry-fitting. For permanent use, dab wood glue along the inside of each finger joint before the final tap-together. The kerf compensation is conservative, so if the fit is too tight, increase the finger width slightly or sand the joints lightly.

Do I need to create an account?

No. The Laser Cut Box Generator is browser-based and completely free. No sign-up and no account; your design work happens right in your browser. Designer Bee keeps only anonymous usage stats, like which settings get exported, to keep improving the tools.
