Does the box generator account for kerf?

Yes. Finger-joint dimensions are offset by your saved kerf automatically so the tabs and slots press-fit instead of falling apart or jamming. Measure your kerf once with the kerf calculator and it carries over.

Are the dimensions inner or outer?

You enter the inner dimensions of the box. The generator adds material thickness and joint geometry on top, so the usable interior matches what you typed.

What box styles are available?

Open tray, divided tray, and sliding-lid box. Each downloads as a single cut-ready SVG laid out flat for your laser bed.

Is the box generator free?

Yes. It is free and runs in your browser. Enter your dimensions and download the SVG, no signup required during beta.

A box generator that actually fits

Most free box generators ignore the one thing that decides whether your box snaps together: kerf. Because the laser removes a sliver of material on every cut, finger joints come out loose unless the tabs and slots are sized for your exact beam. This generator offsets the joints by your saved kerf automatically, so the parts press-fit the first time.

Pick a style, type your inner dimensions, and download a single cut-ready SVG laid out flat for your bed. Everything runs in your browser and nothing is uploaded.

How to use the box generator

1. Pick a style

Open tray, divided tray, or sliding-lid box. The live preview updates as you choose.

2. Enter inner dimensions and thickness

Type the inside width, depth, and height you want, and set your material thickness. The generator adds the walls and joint geometry around your interior.

3. Download the cut-ready SVG

Joints are already kerf-compensated using your saved value. Import the SVG into your laser software and cut. If you have not measured your kerf yet, use the kerf calculator first.

Are dimensions inner or outer?

You enter the inner dimensions. Material thickness and joint geometry are added on top, so the usable interior matches what you typed.

What thickness can I use?

Any thickness your material profile is set to. Joint width scales with thickness, so set it accurately for clean tabs.

Is it free?

Yes, and it runs entirely in your browser with no signup during beta.
