Finger joint box generator
Enter the inside dimensions, material thickness and kerf and get a ready-to-cut finger joint box with a lid in SVG or DXF.
Inside dimensions
The generator adds the wall thickness for you, so the thing you measured fits inside.
Kerf compensated
Every outline is moved out by half the kerf, so the joints are tight without glue.
Ready to cut
One CUT layer, closed outlines, millimetres. Opens in LightBurn, xTool, Glowforge, RDWorks and CAD.
In short.
Are the dimensions inside or outside?
Inside. Enter the space you need; the generator adds the material thickness on every side.
What kerf should I use?
Most diode lasers cut about 0.1 to 0.2 mm in 3 mm plywood, CO2 lasers about 0.15 to 0.25 mm. Cut a 20 mm test square and measure it to be sure.
Can I sell boxes made with this generator?
Yes. The files you generate are yours to use for any purpose, including selling the boxes.
Which file should I download?
SVG for LightBurn, xTool Creative Space and Glowforge; DXF for RDWorks, LaserCAD and CAD programs. Both are in millimetres.
