Free Finger-Joint Box Maker for Laser Cutters

Design precision laser-cut boxes online with kerf-compensated finger joints. Generate SVG cut files for gift boxes, enclosures, and custom storage.

How do you make a finger-joint box file for a laser cutter?

Enter the box width, depth and height, your measured material thickness and your laser kerf in Box Maker, check the assembled 3D preview, and download flat-packed SVG or DXF panels. Kerf compensation keeps the fingers snug instead of loose by one beam width per joint. Box Maker is free, runs in the browser and needs no account.

Frequently Asked Questions

Is Box Maker really free?

Yes — completely free, in your browser, with no account and no credits. There is no watermark and no export limit.

What is kerf and why does the box need it?

Kerf is the width of material the laser burns away, typically 0.1–0.2mm. Box Maker compensates for it so finger joints press together snugly instead of ending up loose by exactly one beam width per joint.

How do I measure material thickness correctly?

Measure with calipers rather than trusting the nominal size — "3mm" plywood is routinely 2.7–3.2mm, and finger joints will not close if the entered thickness is off by more than about 0.2mm.

What files does Box Maker export?

Flat-packed SVG and DXF cut files that import into LightBurn, EZCAD, and any other laser software. You can preview the assembled 3D box before downloading.
