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!
Thanks, I’ll look into that. Keep in mind I specifically designed the speakers (at least the box) to be printed without infill by creating a uniform wall thickness throughout. That is just to avoid the awkward wall-infill-wall combination, when it’s supposed to be a hollow box with thin solid walls.
