Here is a simple new method on how to make a PCB with your 3d printer. It doesn't use a CNC milling attachment but a simple sharp metal rod attached instead of an extruder which scrapes away permanent marker layer form a standard copper PCB blank.PCB is then finished in ferric chloride bath.
Video of the process:
Very detailed step-by-step tutorial and .stl for the K8200 rod attachment (you will have to redesign it for other printers):
