Phone Mounting system for Generick Joystick
The good changes were more due to the fact that my controller is a Thurderbolt 50S and it has some more buttons and inputs, I need to adapt them so that the system does not interfere with the buttons as you can see in the photos.
Other modifications were because I didn't want to use printed screws for the fixing system, so I adapted a back piece to receive an elastic band.
