STL Speaker Grille Models for 20 mm Drivers

This collection gathers STL files for speaker grilles and related parts around 20 mm drivers. You will find parametric covers, honeycomb patterns, fan vents, and mounting rings. It helps you find a starting point for 3D printing and then adapt the geometry to your own driver. 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 Speaker Grille Models for 20 mm Drivers»

The models range from simple flat grilles to parametric covers that change with a few dimensions. Honeycomb and hex patterns are common for woofer protection, while fan and vent grids use a more open mesh. Mounting rings and spacers often appear alongside grilles when a driver needs a raised or recessed fit.

Before printing, check the outer diameter, hole spacing, and the depth the grille adds to the front of the driver. Look at the number of parts and whether the design needs supports or a specific material. The author's page usually lists recommended layer height, wall count, and photos of real prints.

If a search is too narrow, try related terms such as speaker cover, driver grille, mesh, or acoustic cloth. You can also search by driver size, mounting pattern, or the type of enclosure you are building. Combining a grille term with a printer or material term often brings up more results.

FAQ

Frequently asked questions

What measurements matter most for a 20 mm speaker grille?
The outer diameter, the screw or clip spacing, and the depth of the grille are the main ones. Also check the opening size so the sound path is not blocked.
Can I scale a speaker grille STL to fit a different driver?
Scaling changes wall thickness and hole sizes, so it may not fit the mounting points. It is often better to edit the parametric source or adjust the model in CAD.
Which materials are often used for small speaker grilles?
PLA, PETG, and ABS are common in shared designs, but the author's page may list a preferred material. Consider how much heat the driver produces and how the part will be mounted.
How do I find grilles for fans or vents instead of speakers?
Search for fan grille, vent grid, or mesh cover. Many designs share the same honeycomb or hex pattern but differ in mounting holes.
