Introduction

I bought a Grom Audio bluetooth module for my 2007 Toyota 4Runner and while the unit itself is excellent, I decided I didn't like the microphone mount. I've installed similar microphone mounts in the past and always found them to be unreliable, especially where I live in Southern Nevada where we see inside temperatures of 150 degrees F (65C) or more as a common occurrence in the summer. Simply put, the double sided tape just disintegrates.

This then is a small project to crate a 3D print part to mount the microphone in a more permanent piece with a more "factory" look.

Part Design

I modeled the part after one of the blank snap-in switch covers. The microphone slides into the back of the piece and is held in by a slight interference fit and a couple tiny dabs of hot glue which also makes it easily removable. It is angled up 15 degrees so that it is essentially pointed at the driver

Print Setup

This piece, as shown, is printed in black ABS at a print resolution of 0.1mm. It is sliced and printed on its side with a support structure set up as follows:

Slicer - Cura

Overhang Angle - 70°

Support infill - 24%

Here is a picture of how it looks in Cura:
