PS2 rubber pad reverse engineering

This is an example of buttons and D-pad using some PS2 conductive rubber pads.
This design is meant to be used in others projects.

I was working on a new handheld video game project, and to keep the thickness as small as possible I have decided to use some PS2 rubber pads to design the buttons as they are cheap and easy to source online.
But it is quite hard to find any resources about that on the internet, so I had to make my own designs.

I have created and tested this design for handheld video games devices. I'll use it on my next project to save some space. This design only takes less than 5mm between the housing and the PCB, and the buttons feel like some real video games controllers.

I now share with you all the files needed to create buttons with these rubber pads, especially the CAD files of the rubber pads and the files of the butons and D-pad. I hope you'll find that helpful!
