Balun and Unun 3D Models for Antenna Projects

This collection gathers STL files for balun and unun hardware used in antenna projects. You will find enclosures, dipole centers, choke mounts and related parts. It helps when a ready-made housing does not match your wire layout or mounting point. 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

«Balun and Unun 3D Models for Antenna Projects»

The results cover several related parts: boxes and lids for baluns or ununs, center pieces for dipole antennas, choke housings, and brackets that attach a balun to a mast or boom. Some files are simple holders, while others include lids, wire winders, mounting holes or openings for connectors. Parametric versions let you adjust dimensions before exporting an STL.

When choosing a model, check the listed core size, wire gauge and winding space, because these determine whether the part matches your build. Look at the number of printed parts, how they join, and whether screws, inserts or seals are required. On the author's page, review photos of actual prints and any recommended material or print settings.

To narrow the collection, try related terms such as unun, choke, dipole center, end-fed antenna, antenna mount or toroid enclosure. If you need a specific winding style, search for the core family or the mounting method rather than a single title. Combining a part type with a material or printer process can also surface different designs.

FAQ

Frequently asked questions

What is a balun box used for in an antenna build?
It houses the transformer or choke and gives the winding a fixed place. The box also provides points for mounting and for connecting the antenna and feed line.
Which details should I check before printing a balun enclosure?
Check the core size, wire gauge, winding layout and the openings for connectors. Also review the number of parts, assembly method and any listed print settings.
Can I adapt a balun model to a different core or wire?
Some files are parametric and allow dimension changes before export. For fixed models, you may need to scale or edit the mesh, but check that walls and holes remain thick enough for your material.
How do I find unun or choke models in this collection?
Use search terms such as unun, choke, dipole center, end-fed antenna and toroid enclosure. Related terms like antenna mount or wire winder can also reveal matching parts.
