Arcade USB Joystick - One button left

I was looking for a simple single button solution to replicate my all time favorite Amiga Joystick, Tomahawk by Greek company Aneroussis Control. (http://www.atropos-studios.com/External/joysticks/Tomahawk.jpg). Since I couldn't find anything close, I remixed this design to be with a single button, because that's all I need to play my all time retro classics.

P.s. Please note that most arcade usb joystick kits comes with big and small buttons, in this design it is used the smaller one. (Approx. Socket diameter 23,4mm). The original design uses M4 screws and I kept it that way.

Ps.2. I know many will say that the button is on the wrong side, but this is how I grew up playing hence the preference :) Someone else might find this side of the button useful as well.

Many thanks to original creator.
