STL Cases for Voltage Regulators and DC-DC Converters

This collection gathers printable enclosures for voltage regulators, DC-DC converters and related power modules, from small board boxes to larger wall-mounted housings. It is useful when a bare circuit board needs a shell, a display cutout or a mounting point before it goes into a 3D printing queue. Most files are STL meshes that can be scaled or edited to match a specific board. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«STL Cases for Voltage Regulators and DC-DC Converters»

The models split roughly into two groups: compact boxes built around a converter or charger board, and larger housings for mains-powered regulators and relay units. Compact cases often include openings for a display, a potentiometer, screw terminals or a USB port, while larger ones are usually split into a base and a lid and may be shaped for wall or panel mounting. Some designs are simple shells, others add vents, cable channels or switch cutouts.

Before printing, read the model page: board dimensions and hole spacing, the number of parts and how they join, whether supports are needed, and the material and settings the author lists. Photos of real prints help you judge wall thickness and the clearance around connectors. For mains-powered circuits, decide on cable routing and ventilation before starting the print.

Search results improve when you combine the board name with case, or use terms such as enclosure, housing, shell or box. Related queries include buck converter, boost converter, adjustable power supply, voltage display and terminal cover. Adding a mounting type, for example wall mount, DIN rail or panel mount, narrows the list further.

FAQ

Frequently asked questions

What should I measure before printing a case for a voltage regulator?
Measure the board length, width and height, the distance between mounting holes, and the position of connectors, displays and switches. Compare those figures with the dimensions given on the model page.
Do these cases need supports?
It depends on the design: some are shaped to print flat, others have overhangs around connector openings. The author's description and photos of printed parts usually show the orientation that was used.
Can one case be used for several converter boards?
Only when the board outlines and hole spacing match. Boards with the same function often differ in size, so compare dimensions rather than names.
How do I search for a case for a particular module?
Combine the module name with case, enclosure or housing, then add a feature such as display, terminal, switch or wall mount to filter the results.
