3D Models for Speaker Grilles and Fan Covers

This collection gathers STL files for round speaker grilles and protective mesh, mostly sized for 165 mm drivers, alongside fan grilles, vent covers and grill-shaped parts for other uses. It is useful when you need a cover, guard or trim piece that matches a diameter you already have. Each entry is a starting point for 3D printing, so the exact geometry still has to be checked against your own part. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«3D Models for Speaker Grilles and Fan Covers»

The models fall into a few groups. Speaker grilles and honeycomb mesh covers dominate, usually built around a 165 mm or 6.5 inch driver. Fan grilles and vent covers for PC cases and enclosures form a second group, and there are also BBQ grill parts, scale grill props, automotive speaker mounts and small intake guards for RC aircraft. The groups differ mainly in what they attach to: a driver frame, a case panel, a chassis opening or a scale model.

When choosing a file, compare the stated outer diameter and the mounting hole spacing with your own measurements, since a nominal size rarely matches a real cutout exactly. Look at how thick the mesh or ribs are, how many separate parts the model has, and whether the author shows supports in the print orientation. The model page usually lists the material and settings used, and photos of finished prints tell you more about surface quality and fit than a render does.

To widen or narrow the search, try synonyms such as speaker cover, woofer grille, mesh guard, honeycomb grille, fan filter or vent cover, and add the diameter in either millimetres or inches. Related topics worth checking are cabinet trim rings, gaskets and spacers, case fan filters, and scale accessories for dioramas. If a result set is too broad, combine the part name with the mounting context, for example a case model or a driver size.

FAQ

よくある質問

What does 165 mm mean for a speaker grille?
It is the nominal diameter of the driver, roughly 6.5 inches. Measure the actual cutout and the screw hole spacing on your cabinet, because the nominal figure and the real opening often differ.
Do printed speaker grilles need supports?
It depends on the geometry: flat mesh panels with a rim usually print without them, while domed or recessed shapes may need them under overhangs. The author's print orientation and photos show what was actually done.
Which material is used for grilles and guards?
Authors commonly list PLA or PETG on the model page, and the choice often follows the heat and load at the mounting point. Check the listed material and settings rather than assuming one works everywhere.
How do I find a grille for a different driver size?
Search with the diameter in both millimetres and inches, for example 100 mm and 4 inch, and add words like mesh, cover or guard. Scaling an existing file is possible, but hole spacing and mesh thickness scale with it.
