Question 1

What does the SVG export contain?

Accepted Answer

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.

Question 2

What material thickness should I use?

Accepted Answer

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.

Question 3

Do the panels need glue?

Accepted Answer

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.

Question 4
