Parametric 6x9 Speaker Spacer

*** NEW VERSION - Now includes mounting tabs!!!! ***

*** OVERVIEW ***
A speaker mounting bracket for 5x7/6x8 and 6 x 9 speakers (the STL placeholder is only an example). My goal is to enable 3D printing of speaker adapters for a wide range of vehicles.

I have seen several mounting adapters for 6.5-inch speakers, but not much for 6x9 speakers. MDF is no longer the best material for speaker rings, as it can get wet and break up. Some manufacturers offer plug-and-play plastic rings, but they are often thin and prone to vibration, which can damage speakers. 3D printed speaker spacers are a great alternative! It's best to print these with a filament that withstands heat, such as ASA, PETG, or ABS.

*** Features: ***

• Units in inches or millimeters (If you are using inch measurements, you put 6.0 X IN and the program will convert it for you)
• Selectable resolution of the model, use a low resolution while making changes, use a high resolution to render before exporting
• Can make the bracket with speakers flush-mounted for 6x9 speakers
• Can make a lip around the bottom of the bracket, which can also be offset

Use OpenSCAD to make your adapter the exact size you need. It's easier, faster, and much more robust to use OpenSCAD than the customizer.

To export the model from OpenSCAD, press F5, then F6, then go to File>Export>Export as STL.

UPDATE: 12/24/2025. Now includes configurable mounting tabs and selectable speaker size for 5x7/6x8 and 6x9 speakers.

UPDATE: 10/18/2023, There are many updates to the OpenSCAD file. I'm still working on a good way to make mounting tabs. I have corrected the areas that were making it difficult to switch between inches and millimeters. To use millimeters make sure to change every measurement to millimeter measurements. Google is able to convert units easily.

UPDATE: 10/13/2023, I'm calling this a work in progress now. There is no provision for mounting this into a vehicle so I'm going to make some changes soon for that. If any of you OpenSCAD gurus have some ideas please let me know. I only have rudimentary skills in OpenSCAD at this point. The STL generated can be imported into something like Tinkercad and mount holes or tabs can be added.

UPDATE: 10/9/2023, There are now two versions of the SCAD file. One for imperial measurements and the other for metric. This will help out a lot because converting units was proving to be difficult.

A few other changes are the addition of measurements for the outside size of the ring; fixed the size of the speaker mounting holes as suggested by koukimonster91 in the comments; and the last change is you can specify the depth of the speaker mounting holes.
