Created my own mounting box as I had a video phone built-in earlier where the wall opening / box didn't fit anymore for my new one (Bticino - Linea 3000). This is just the first part, more parts to come. Not so much sharing for the design itself but more for the print result of using a new material (at least for me) called ApolloX from Formfutura. I used below settings and was pretty happy with the results. No warping at all. Did see little bit during creation of the brim - you can also see crack in picture - but it did not at all negatively affect the final print. If it will now withstand outside conditions like rain, UV, heat, cold, ... this would be a pretty neat filament! Thanks @Tinkergnome for bringing this up to my attention!
