Laser Cut Box Generator

What the box generator makes

The Boxes studio draws every panel of a finger-jointed box from four numbers: width, depth, height and material thickness. It works out the fingers on each edge so they interlock at the corners, adds kerf compensation so the joints are tight, and shows the result as a 3D assembly you can pull apart with the Explode slider before you cut anything.

You can start from scratch or from a preset. The presets fill in sensible sizes and options for common projects, and you can change anything afterwards:

• Drawer organizer, board game insert and seed packet organizer
• Tea box with 8 slots and a recipe card box for 4 × 6 in cards
• Wine bottle gift box, wine bottle carrier for four bottles and a six-pack carrier
• Dice box, dice rolling tray and card deck box
• Napkin holder and coin bank with a slot in the lid
• Rounded box, where the walls bend on living-hinge cuts

Material thickness and kerf: the two numbers that matter

Most failed boxes come down to one of two things. The first is thickness. Plywood and MDF vary from sheet to sheet, so measure the actual sheet with calipers in a couple of places and type in what you see. The generator sizes every finger and slot from that number.

The second is kerf, the width of material the beam burns away. Without compensation every finger comes out slightly narrow and every slot slightly wide, so the joint rattles. Measure your kerf once per material with the kerf test, enter it in Boxes, and the fingers grow by half the kerf on each side so they press together snugly.

Lids, dividers and corners

Choose an open tray, a closed box or a lift-off lid with a lip that keeps it in place. Dividers can run across the width, the depth or both; crossing dividers slot together with half-lap joints so they sit flat.

The corner style changes how the box is built:

Corner style	Best for
Finger joints	Classic boxes, the strongest glue-free joint
Tab & slot	Quick assembly with a few wide tabs; good for large boxes and displays
Rounded (living hinge)	Soft corners where the wall bends; use thin, flexible plywood such as 3 mm

Extras include a carry handle, which turns an open box into a bottle or six-pack carrier, a finger scoop for napkin holders and card boxes, and engraved labels on the panels.

Exporting and cutting

The export gives you each panel as its own file plus one sheet with every part, in real millimetres. With the LightBurn or xTool preset, cuts, scores and engraving land on separate layers, so you set power and speed once per layer. If you don’t know the right settings for your material yet, cut a test card first; it is quicker than recutting a whole box.

Before you send it to the laser:

1. Check the 3D view with the Explode slider so you can see every part and how it fits.
2. Cut one corner test (two small panels) if you are using a new material or a new kerf value.
3. Cut the full box, cut side up, and assemble from the base outwards.

Common problems

The joints are loose. Your kerf value is too small or the material is thinner than you entered. Re-measure both.

The joints won’t go together. The kerf value is too large, or the sheet is thicker in places. Reduce the kerf by 0.02 to 0.05 mm and test again.

The box isn’t square. Check that the parts didn’t shift on the bed, and that the corners are fully cut through. A hinge or rounded box needs the hinge pattern cut cleanly or the wall won’t bend evenly.

Selling boxes

Boxes are a popular product because one design can be resized for many uses. Before you list one, run the numbers in the laser price calculator: material share of the sheet, laser time, assembly time and packaging add up faster than you might expect.
