Fully Parametric Custom Speaker Grills
If you are into car audio fabrication, custom speaker builds, you know that finding a grills with the exact diameter, thickness, and hole spacing you need is a massive headache.
As a dedicated car audio guy, I build a ton of custom grills for subwoofers, door speakers and cooling vents. Tired of fighting with basic 3D shapes in Tinkercad every time I needed a slight size tweak, I coded this fully parametric generator in OpenSCAD. Now you can customize and download the perfect grille in seconds!
🛠️ What Makes This Model Awesome?
Unlike static STL files, this model is 100% parametric. Using MakerWorld's MakerLab / Parametric Model Maker, you can adjust everything on the fly:
- 3 Distinct Mesh Patterns: Choose between Honeycomb (classic hex), Grid (clean square mesh), or Circles (staggered bubble pattern).
- Fully Adjustable Outer Rim: Dial in the exact outer diameter, rim width, and total thickness.
- Smart Mounting Holes: Set your screw hole count (from 0 to 24), hole diameter, and edge spacing. The code automatically spaces them symmetrically!
- Custom Edge Chamfers: Add a smooth 3D chamfer to the top, bottom, or both sides of the outer rim to give your build a highly polished, professional finish.
🎛️ How to Customize Your Grills
- Click the Customize button here on MakerWorld.
- Main Dimensions: Put in your target outer diameter and desired plate thickness.
- Pattern Settings: Swap between honeycomb, grid, or circles, and adjust the cell size and wall thickness to control how "open" or "dense" the mesh is.
- Chamfer Settings: Set your chamfer size (e.g., 1mm or 1.5mm) and choose where you want it (e.g., select top to give your mounting screws a slightly countersunk look).
- Mounting Holes: Set the exact number of mounting screws your speaker or vent frame requires.

💡 My Car Audio Print Recommendations
Because these grills are often used in demanding environments (like hot car interiors or high-vibration speaker enclosures), here are my personal fabrication tips:
⚠️ Material Choice: If you are installing this in a vehicle, do not use standard PLA—it will warp on a hot summer day. I highly recommend printing in ASA or PETG for excellent heat and UV resistance. (I use PETG i had no problems even in hot summer days on 40+ degrees in the car)
- Wall Loops: Set to at least 4 or 5 walls to ensure the thin honeycomb/mesh lines are printed solid and strong.
- Infill: 15% (since the model is thin, the walls and top/bottom layers will make up the entire print anyway).
