Customizeable Speaker Bar Grill Version 2

This is a new version of my previous Customizable Speaker Bar Grill. https://www.thingiverse.com/thing:7049220

This version is more user-friendly and consolidated into a single OpenSCAD file. It is compatible with the Thingiverse Customizer (although it did not function reliably during testing). In my opinion, the best experience is to download the included OpenSCAD file and customize it directly.

You can download OpenSCAD from here: https://openscad.org/
