Some parts, such as the personalized magnetic fixing faceplate to cover the loudspeaker screws, have been made of nylon PA11 with SLS technology 3D printing. I also experimented with nylon PA12 printed with MJF technology. Both solutions provided excellent aesthetic and mechanical results. In this last aspect, nylon PA12 in particular, has a resistance comparable to that of injection molded ABS and I used it for the clamp plate.
