For maximum stiffness, I printed these without infill, all perimeters. The filament is Greentec Pro CF.

I got the general specifications from the book "Mastering the sound of the acoustic guitar" by Giuliano Nicoletti.

These are mainly for playing a test tone and generating chladny patterns at different stages of guitar making, but they also sound surprisingly good as desktop speakers!

Check out my post here for information about infill percentages. Doing solid parts is usually a waste of time and material.
