This is version 2 of the gamepad http://www.thingiverse.com/thing:1663661
The wiring will be somewhat similar.

The new spring design provides more resistance and works in the direction of the movement of the button. The cross is now one piece, including its four springs.

The assembly has become much easier. I haven't tested the wiring yet.

Still, you may need hot glue to fix cables and wires (maybe I will work out a cable system to avoid that in the future)

Anyways, I hope the button-thing provides some inspiration for your future projects!

Printrbot

Simple Black

0.1-0.2mm

sometimes :P

I printed bottom and top with 0.2mm and 15% infill

The side elements (top. back, left and right) were printed without infill and 0.2mm

Springs and Cross, have been printed with 0.1mm without infill

for the buttons I used supports, 0.1mm and no infill.
