A case for an 85 × 56 mm board with openings for its ports

The base and the lid, ready to print side by side

Seen from above

Size: the case is 92 × 63 × 26 mm. There are two parts, the base and the lid, laid 8 mm apart. Files:

• model.stl and model.3mf for printing;
• model.obj and model.glb;
• outline.dxf;
• model.js, with the board's size, its holes and every opening as named numbers at the top;
• a README.

The README tells you to check the openings against your board before printing. The lid's lip has a 0.3 mm gap, so it sits on without force.

Client: a hobbyist building a small home server on a single-board computer. Task: a case for a board of 85 × 56 mm with four M2.5 holes 3.5 mm from its edges. It needs three openings on the long side for two USB ports and a network port, two on the short side for power and video, and a lid with vent slots that sits on with a lip.

The client and all details are made up.

About this service

A 3D model of a box for a project built on an Arduino or ESP32 board or a similar microcontroller board: a weather display, a timer, a small controller for your hobby. It has a base with posts at the mounting holes, a lid, and openings for the USB port, a power socket, buttons, a switch, LEDs and a display window, placed from your measurements. A project often has several pieces, such as a board, a display and a sensor, so you give the size and holes of each, the height of the tallest part with its pin headers and wires, and where the cables come out. You get a ZIP archive with STL, 3MF, OBJ, GLB, a DXF outline, the code with the sizes at the top, a README with printing advice and pictures from four sides. It is for low-voltage projects: no mains voltage inside, no wiring and no waterproof rating. A battery and its charging are yours; we leave the room you ask for.

What is included

• What you getA ZIP archive with model.stl and model.3mf for 3D printing, model.obj for 3D editors, model.glb for viewing on the web and in augmented reality, outline.dxf with the outline seen from above, model.js with the sizes of every board and opening as named numbers at the top, a README with printing advice and 4 PNG pictures from four sides, also shown on the order page. The base and the lid lie side by side, ready to print separately.
• Posts for boards and modulesAt the holes you measured; up to 6 in Premium
• Display window and buttonsSized to the visible area and the buttons you give
• Room insideHeight for pin headers, wires and a battery holder of your size
• USB within reachAn opening at the board's port, so you can program it with the lid on
• A fit gap and solid walls0.2-0.4 mm between the base and the lid, walls of at least 1.2 mm

How it works

1. 1
   Parts and sizesYou send the size and holes of each board and module, and the openings
2. 2
   3D modelWe build the 3D model and check that it is a closed solid of the sizes you asked for
3. 3
   Try the boardYou check the pictures and the README and print the base first to try the board in it
4. 4
   ChangesYou send what to change, with measurements, within your package

What we need from you

Every board and module that goes inside: its length and width in mm, its mounting holes measured from one corner, and the height of its tallest part, including pin headers and plugged-in wires. For a display: its outer size, its visible area and its holes. For buttons, switches and LEDs: their diameter and where they go. Where the USB cable or power comes in. If there is a battery holder, its size. A sketch of how the parts sit inside, or a photo from above with a ruler, helps. How the lid should hold, and the material if you know it.

We will ask you:

• Which boards and modules go inside?
• Sizes and holes of each, in mm
• Which openings are needed?
• Lid, cables and place
• Your printer and material
