This free STL is an example configuration of a 3D printable wall enclosure for sensors, IoT electronics and custom PCB projects.

The STL provided here has fixed dimensions. If your circuit board, mounting holes, sensor or cable connection is different, you can generate a custom version using the online configurator.

Create an enclosure for your electronics

The customizable version allows you to adjust:

PCB Width & Length

Set the enclosure according to the dimensions of your circuit board.

Component Height

Adjust the internal space for components mounted above the PCB.

Mount Spacing X & Y

Match the internal mounting points to your PCB hole pattern.

PCB Hole Diameter

Set the mounting-hole diameter.

Sensor Opening

Create a centered round opening for a sensor. Set it to 0 to create a closed front.

Cable Opening Width & Height

Create an opening for USB cables, power cables or other connections.

Wall Mounting Style

Choose between:

concealed keyhole mounting

external mounting tabs

no wall mounting

This makes the enclosure useful for many DIY electronics projects, including sensor nodes, ESP32 projects, environmental sensors, smart-home devices, IoT controllers, monitoring systems and custom PCB projects.

No CAD required. Enter your measurements, generate the model and download your custom STL.
