How to use Box Studio
Box Studio generates laser-ready SVG files for finger joint boxes in three steps. No desktop software, no account required.
1
Set dimensions
Enter width, height, and depth in mm or inches. Choose between interior, exterior, or cell-based sizing depending on your needs.
2
Configure joints & kerf
Select finger joint size and enter your machine's kerf value. The tool compensates automatically for a tight press-fit result.
3
Preview and download
Rotate the 3D preview to verify every panel. When satisfied, download the SVG — it's ready to import into LightBurn or any laser software.
What is kerf and why does it matter?
Kerf is the width of material removed by the laser beam during cutting. It typically ranges from 0.10 mm to 0.25 mm depending on the machine, material, and settings. Without accounting for kerf, finger joints will be loose — the panels won't hold together without glue.
To find your kerf: cut a 100 mm square from your material, measure it with digital calipers, and calculate (100 − measured) ÷ 2. Enter that value in the Kerf field. Box Studio compensates the joint geometry automatically. You can also use the Kerf Calculator tool.
Finger joints, finger holes, and flat — which to choose?
Finger joints are the standard option: rectangular tabs interlock across all four edges. Best for boxes that need to be strong and flat when laid out for cutting. Finger holes insert side panels into rectangular cutouts in the front and back panels — useful when you want the sides to slide in and out. Flat outputs panels with no joints at all — for when you'll assemble using glue, snap-fit hardware, or your own joinery.
Adding internal dividers
Use the Dividers section to add a grid of internal compartments. Set rows (Y) and columns (X) to create a uniform grid, or switch to custom positioning to place each divider at an exact mm offset. The dividers slot into each other using half-depth cross-cuts, and into the box walls using the same finger joint system.
Recommended materials
Box Studio works with any flat sheet material your laser can cut. These are the most common choices:
MDF (Medium Density Fiberboard)
The most popular choice for laser cut boxes. MDF cuts cleanly, has consistent thickness, and holds finger joints well. 3 mm MDF is ideal for small to medium boxes. Use 6 mm for larger boxes that need structural rigidity. Always use ventilation — MDF releases formaldehyde when cut.
Plywood (Baltic birch / Laser-grade)
Stronger than MDF and has a natural wood grain appearance. Use Baltic birch or laser-grade plywood — standard construction plywood contains voids and adhesives that cause uneven cuts. 3 mm and 4 mm thicknesses are most common for box making.
Acrylic
Produces clean, polished edges and a professional finish. Cast acrylic cuts better than extruded. Acrylic requires lower speed and higher power than wood. It releases toxic fumes — mandatory fume extraction. Kerf values with acrylic tend to be slightly lower (0.10–0.15 mm) than with wood.
Which thickness to use?
For most desktop laser cutters (CO2 40–80W, diode 20–40W): 3 mm is the standard. It cuts in a single pass, produces well-proportioned finger joints, and is easy to source. Use 6 mm when you need structural strength or larger finger tabs. For miniature boxes or detail work, 2 mm works well with smaller finger sizes (4–5 mm).
Compatible software
The SVG files generated by Box Studio are standard vector files that work with any laser cutter software:
⚡ LightBurn
🔵 xTool Creative Space
LaserGRBL
RDWorks
Inkscape
Adobe Illustrator
EZCAD
K40 Whisperer
Import the SVG as-is. Each panel is a separate closed path. In LightBurn, assign the cut layer (black strokes) to your cut profile. No grouping or ungrouping needed.
Frequently asked questions
My joints are too tight / too loose. What do I adjust?
If joints are too tight, increase the kerf value slightly (try adding 0.05 mm). If they're too loose, decrease it. A good kerf calibration takes 1–2 test cuts. The goal is press-fit: pieces go together with firm hand pressure and don't rattle.
Can I use Box Studio for commercial projects?
Yes. The SVG files you generate are yours to use for any purpose — personal, educational, or commercial. No attribution required.
Does Box Studio save my designs?
No. The tool runs entirely in your browser and no data is saved to our servers. Your designs are lost when you close the tab. Download the SVG before closing if you want to keep it.
What is the maximum box size?
There's no hard limit in the generator. The practical limit is the bed size of your laser cutter and the sheet size of your material. Box Studio lays out all panels flat — if a panel is larger than your bed, you'll need to split it manually in your laser software.
Why does the 3D preview look different from the SVG layout?
The 3D preview shows the assembled box. The SVG shows all panels laid flat for cutting — that's how they'll look in LightBurn before you fold and assemble them. Both are correct; they're just different views of the same design.
Is Box Studio really free?
Yes, completely free. No subscription, no usage limits, no watermarks on the SVG files. The tool is supported by ads. If you find it useful, the best way to support it is to share it with other makers.
