Sharpie Pen Plotter
In the quest to get RepRap to be able to print more and more of its own parts, we are attempting to be able to draw circuit board traces with a sharpie based pen plotter in order to later etch the boards. This would save lots of money as we would no longer need to buy expensive PCB (printed circuit boards) and instead could print then etch our own.
You need to print both the spring pen mount: [1] and the flexy shaft holder: [2]
"Printing" PCBs
A substrate with a copper top layer is drawn on and placed in acid to etch away the copper not drawn over thus creating your traces. This page does a great job explaining in depth how to print your own PCBs: [3]
Current generation RAMPs boards cannot be easily etched at home but version 1.25 or lower can using utilmachine's instructions.
Universal Pen Holder for Mendel
This is a set of files for a Universal Pen Holder made to be mounted on a Mendel Unit. As it is currently designed, you would also need a 6/32 threaded rod and at least 4 nuts of the same type. You also need 6 screws that will be threaded into the holes in the hexagon shaped parts. These screws are used to hold the pen in place, use whatever screws can screw snugly into the holes.
