I have printed it in ABS with a 0.4 nozzle using 4 wall layers and 5 layers top/bottom, resulting in zero infill. Top printed upside down, no supports. Base printed with support.
The author remixed this model.
Slight changes to the base made by fns720 and a fitting top that is meant to protect the sonos 1 from weather/rain. The mounting tabs are the same and can be found in the original post.
