DIN Rail PCB Enclosure – Customizable Electronics Case STL

Need a DIN rail enclosure that actually fits your PCB?

This free STL is a ready-to-print example of a DIN rail PCB enclosure for electronics, controllers, sensors and custom circuit-board projects.

The uploaded STL uses fixed dimensions. If your PCB, mounting holes, components or terminal layout are different, you can generate your own custom version online:

With the online configurator you can adjust:

PCB Width & Length – match the enclosure to your circuit board

Top Component Height – allow space for components above the PCB

Bottom Component Height – control clearance below the PCB and standoff height

Hole Spacing X & Y – match the mounting-hole pattern of your PCB

PCB Hole Diameter – adapt the mounting points

Terminals per Side – create centered terminal openings on the long sides

Terminal Opening Width – adjust the openings to your connectors

Lid Ventilation – choose between a closed lid or ventilation slots

This enclosure is useful for DIY electronics, automation projects, control cabinets, sensor modules, microcontroller projects, relay boards and other DIN-rail-mounted electronics.

No CAD required. Enter your dimensions, generate the model, preview it online and download the custom STL.
