I was playing a video game on my PC and found that my poor little fingers were getting sore from pressing the WASD keys. Since I am playing this game a lot perhaps I could find a way to ease the pain by using a joystick or gamepad. I already have a couple of old gamepads lying around that won't work due to compatibility issues so I was reluctant to buy a new one. So I made a little joystick that can be placed on the keyboard. It is light weight and portable, no cables to plug in and there is no need to download any drivers. Just set it on your keyboard and it is ready to go.
Bonus: I created a 3d model of the joystick. See step 5 below!
