Hello, I doing the retro-gaming. I trying to do L&R CONDUCTIVE button for my GameBoy (classic one). The problem that i never do it before and dont know how to set a size of my board. The most big problem for me it's to keep the exactly localisation on my OCB board of my holes (for screws or soldering wires), and localisation between two buttons etc. I've done a 3D model of my PCB board (if some one would like to see). Can somebody help me please. PCB size : 55,60 X 15,5![enter image description here][1] Thanks [1]: /editor/20171026/59f122d44eb76.jpg
