This is a DIY wired game controller that I designed and built myself It uses 2 mechanical keyboard switches for the right and left trigger buttons and 2 joysticks for other stuff

The uploaded STL's are slightly different to the ones shown in the photo's because they are improved with better ergonomics and fixes some bugs but they still retain the same look.

To together the game controller case you need 6 m4 screws longer than 4mm and shorter than 17mm

The controller is designed to house the Arduino pro micro which is glued onto the stand/block sitting in front of the usb port whilst the joysticks sit on the 2 circular pylons which you need to align yourself to match the holes
