Nuts inserted, battery, USB cables and screens fixed, Pi3 screwed down. Correction of speaker holes. I had to file them down and will add a cover on top. I will correct the design to avoid this in the future. In the original design I put a grid that was very thin and it broke when removing the supports on the printer.

I have also reprinted the body of the lenses, to add more thickness on the face that contacts the screen. It has also been printed better.

I had to enlarge the raspberry mounting holes from M2 to M3 with a round file
