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.
I used Prusa Orange PETG.
It fits very tight with the bed support, so keep in mind to smooth it with a rasp if necessary.
