Prusa i3 Mk3 Raspberry Pi Camera mount (New extruder)

After update my extruder with the new mount for improve cooling my front fan crashed with the camera mount because it's new position.

I made the arm 1,5cm longer to avoid this problem and I reduced the top part to make it easy to print and make it fit in bed support.

Aslo I updated the back of the camera case in order to improve how it fits with front part so it doesn't open alone.
