Pete has written an article detailing his DIY pick and place machine build:
Above is the back side of the machine. Along the top is a piece of DIN Rail that extends from the left and right of the ShapeOko frame. This is where the majority of parts are installed. Below this, you see a grey vertical surface with parts mounted. This is a long steel L-Bracket, surplus from some IKEA furniture, that I screwed to the ShapeOko MDF work surface.
