Layout
Space-saving layout instead of cross pattern
Box Designer
Create parametric wooden boxes with precise finger joints. Add dividers that are spaced evenly by default or positioned freely. Or choose the enclosed build: the side walls wrap around front and back, bottom and top sit in closed wall slots and the outer edges stay smooth. Made for laser cutters and CNC routers.
Precise finger joints
The optimal finger layout is calculated automatically, with kerf compensation for joints that fit right off the machine. Corners close fully all the way around – or pick the enclosed build with smooth outer edges and optional rounded corners.
Dividers & compartments
Add dividers in the X and Y direction – spaced evenly or positioned by hand. Wherever dividers cross they get half-depth cross-lap slots and simply slide into each other.
Instant export
Export as SVG, DXF or PDF for your laser or CAM software, or as STEP and STL for 3D CAD. All panels and dividers come pre-arranged in a flat cut layout.
Usage tips
- Material thickness: 3–6 mm plywood is ideal for small boxes, 10–15 mm for larger builds.
- Finger width: Rule of thumb: 2–3× the material thickness gives the best mix of strength and looks.
- Dividers: In auto mode the dividers are spaced evenly, in manual mode you place them freely. Crossing dividers automatically get half-depth cross-lap slots.
- Kerf: Typical values: laser 0.1–0.2 mm, CNC end mills 1–3 mm depending on the bit diameter. Cut a small test corner to dial it in.
