How to Make a PCB with Sharp Metal Rod Attachment

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.
