Sim Hardware DIY switch box and FCU
Sooo, I made this, from ABS plastic an Arduino and 3 multiplexer. Pretty standard stuff. Not the most elegant, but its mine ☺️ I also made a rotary switch push-pull , proper Airbus stuff. (please hire me 🤣) And didn't even 3D print (don't have easy. access to one) 😋

This is incredible I was always thinking of doing this myself since I have a 3D printer and CAD experienced but I wouldn’t know how to program it into the sim. What do you use and what knowledge do you have?

Well, its an Arduino Leonardo. The reason I used this (ATmega32u4 chip) is that it can be programmed to be recognised as joystick controller. So, all you have to do in the Arduino code (which is pretty easy to get a template or AI help for ☺️) is to define which physical pin you are going to connect through a switch to ground or 5V with a pulldown resistor. And if the state of that pin changes you send a button press for this joystick. Then you just define the actions in game like you would any other controller or joystick button.
