Electronics Standoff Case

Set the size. Get a laser file.

A closed six-sided case for a circuit board, a microcontroller or a small project. Set its size to your board and PrintCut draws the base, the four walls and the lid, finger-jointed all round.

Type the outside size, or switch to inside sizes when what goes in it matters: PrintCut adds the walls for you. Width and depth go from 25 to 350 mm and height from 15 to 350 mm, or start from a preset: Small, Medium, Large, Pencil or Cube. Pick your material and its thickness, and every part redraws to match. Turn the box around in 3D, assembled or laid flat, before you cut anything.

Joints that fit

Every edge is finger-jointed, and the fingers are drawn for the thickness you chose. Set the finger width (5 to 25 mm) for the look you want, and the kerf (0 to 0.30 mm) for how much your laser burns away, so the joints press together snugly instead of falling apart or needing a hammer.

Closed on every side

All six sides interlock, so the case holds its shape with or without glue. Use inside sizes to fit your board with room to spare, and use smaller fingers for a small case so every edge still gets several joints.

Dogbone corners

Each inside corner of every joint gets a small round relief (0.5 mm radius) cut into the wood. A beam or a bit can leave a corner slightly rounded; the relief takes that corner out, so the square fingers of the next panel seat fully flush. It is on for this case and can be turned off in its settings.

What you get

• Base and lid: finger-jointed on all four edges.
• Four walls: front, back, left and right.

The cut file

Download an SVG for LightBurn, xTool or Glowforge with each kind of line on its own colour-coded layer, a DXF for CAD software, or G-code for GRBL and Marlin machines. The parts are laid out on your laser’s bed for you, with the total cutting length and an estimate of the cutting time. When they need more than one sheet, each sheet is its own file in one zip. Part names are written in small blue text at each part’s corner; untick them if your laser program would burn them.

Built for the machine, not just the screen

• Parts are packed onto your laser’s bed; anything bigger than the bed is split for you.
• Kerf compensation widens every finger and narrows every slot by half the kerf, for a tight friction fit.
• The total cutting length and an estimated cutting time are shown before you export.

Assembly

1. Cut every part.
2. Press the walls into the base.
3. Put your board in, then press the lid on. Leave it unglued if you will open it again.

Cut it from 3 mm plywood or acrylic to protect a Raspberry Pi, an Arduino or a sensor on a shelf.
