This template generates cases with screw-mounted lids.

In addition to the basic parameters (length, width, height), it is possible to define a cooling level on the case, the lid, or both.

Margins for the screw housing and the assembly area are also available for adjustment depending on the material used.

The case requires the use of 4 socket head cap screws (DIN 912) with a diameter of M3.

In the case of FFF 3D printing, minimal support structures will be required around the screw head recesses in the lid.

Additional information

Notes

Note that parameters #1 length and #2 width refer to the external dimensions. If you are working with internal dimensions, you will need to add twice the wall thickness.

Parameter #6 screw margin adjusts the diameter of the cylinder into which the screws thread are inserted in the base. By default, its diameter is 3 mm. Depending on the material used, you will likely need to adjust this value so that the thread cuts into the material properly (not too much, not too little).

Parameter #7 fit clearance defines the gap between the two parts for assembly. At 0, both objects are modeled with no clearance at all. It is often recommended to add 0.1 to 0.2 mm for a smooth fit.

Parameter #8 cooling level determines the strength of the ventilation. At 0, no cutouts are applied. At 10, the maximum possible number of cutouts is generated.

Enclosure with screw-mounted lid and optional ventilation

Enclosures with screw-mounted lids provide a reliable technical solution for protecting, housing, or assembling electronic, mechanical, or experimental components. Thanks to their precise fit and screw-fastened design, these models offer effective protection against dust and impact while allowing repeated opening without wear. Each enclosure features a calibrated clearance fit that ensures perfect alignment, regardless of the printing material — PLA, PETG, ASA, or ABS — maintaining optimal sealing and stability.

For the simplest needs, a non-ventilated enclosure is ideal for protecting sensitive electronic assemblies. Its fully closed design provides excellent isolation, preventing dust or moisture from entering. For a minimal format, a very small screw-mounted enclosure is perfect for sensors, switches, or micro-modules, with a simple and reliable screw lid even in tight spaces.

When heat dissipation or airflow is required, an enclosure with top and bottom vents allows natural and consistent ventilation of internal components. The vent grids are designed to provide sufficient airflow while maintaining lid rigidity and internal protection. At the other end of the range, a large screw-mounted enclosure offers generous volume to house boards, connectors, and wiring while retaining a strong and durable structure.

Whether compact, medium, or large, each 3D-printable screw-mounted enclosure can be customized to match the project’s needs: length, width, height, wall thickness, lid shape, and clearance fit. These enclosures combine strength, modularity, and precision, providing a professional finish for technical builds, engineering prototypes, or long-lasting applications in various environments.
