Sonos Era 100 - Robust Wall Mount

I remixed a previously-found Sonos Era 100 wall mount by adding robust struts on the back and bottom. The original designer notes it's “simple and elegant.” While I loved the design and function, even with PLA+, I found the weight of the speaker caused drooping and it reduced the elegance. An M5 x 12 mm screw is required to fasten the speaker to the base.
