Simulator button box

I wanted to make a button box for use with my flight simulators, mainly IL-2 Sturmovik and FS2020. It is registered in windows as a joystick, and can thus be used in any simulator that supports joysticks.The parts are very cheap, and I also got a chinese Arduino Leonardo from banggood.com.

I went ahead and got some cheap parts from ebay:
-2x on/off toggle switches with cover (12mm diameter)
-8x momentary push buttons (16mm diameter)
-2x rotary encoders (6,8mm diameter)
-4x on-off-on momentary switches (5.8mm diameter)
-6x potentiometers (6,8mm diameter)

I then made a box with predesigned holes for the parts I ordered. It has plenty of room for the wiring and the arduino. I included a lid with no holes in it, in case you have different components and just want to drill holes instead. I used 4x M4 screws to secure the lid to the box itself. If I was to make this one all over, I would probably have bought different on-off-on switches. They work but are a bit flimsy. I got a few
