I could be, would not be the first time!
I am asking, who is running the lines through the walls to the hookups? My understanding is that the conduit will be in between the two 3D printed walls, and you run the wiring through that. But your technician is the one running the wiring?? That is what I don't get. And besides that fact, I still have seen zero evidence of the 3D printed technician doing it.
