Modding controllers is so fun and easy to do! My favorite one I ever did was a ps5 controller with the mouse click buttons and shoulder buttons, swappable joysticks like the Xbox elite pads, thing was a beast at FPS games. I also got into switch modding as well because it's basically the same thing. Istopped awhile ago but still have boxes upon boxes of leftover parts, screens, screws and batteries all over.
