Universal Mounting Plates: 3D Models and STL Files

Mounting plates show up here as flat parts with hole patterns, slots and raised bosses, made to hold a device in place. The collection gathers STL files for electronics boards, handbrakes, cameras, telescopes and desk stands, so you can compare several approaches to the same job. Because the plate is often the interface between two objects, small changes in hole spacing matter more than the overall shape. 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

«Universal Mounting Plates: 3D Models and STL Files»

Plates for single-board computers and small electronics usually keep a low profile and a fixed hole pattern. Handbrake and sim-racing mounts add a raised body or a clamp so the lever sits at an angle. Camera, drone and telescope plates tend toward thicker sections, slots and rails, while desk and charger plates stay mostly flat with cutouts for cables.

On the author's model page, check hole spacing, plate thickness and outer dimensions against the part you want to attach, since a fraction of a millimetre decides whether screws line up. Look at how many separate pieces are involved and whether they need fasteners or glue. Read the material and settings the author lists, along with photos of real prints, to see how the plate is oriented and whether supports are needed.

Search terms shift with the device: try "mounting plate", "bracket", "adapter plate" or "base plate", and add the object it holds, such as a controller, a camera cage, a charger or a tripod head. Related topics like VESA patterns, rail systems or common hole standards narrow results further. If nothing matches, a parametric plate or a blank plate you drill yourself is another route.

FAQ

Frequently asked questions

What is a universal mounting plate?
It is a flat part with holes, slots or rails that can be attached to more than one object. The pattern either follows a common standard or is left open so you can drill or tap it yourself.
How do I check the dimensions of a plate against my device?
Compare the hole spacing, thickness and outer dimensions on the model page with your device. Photos of real prints and any drawings the author includes help confirm the measurements.
Do these plates need supports?
Many are flat and print without them, but plates with raised bosses, clamps or deep cutouts may need supports. The author's page usually states the orientation and whether supports are required.
Which material works for a mounting plate?
Flat plates that carry little load print well in PLA, while parts that take screws or heat are often made in PETG, ABS or a filled filament. The author's listed material and settings are the first thing to check.
