This Pen Holder can be used to draw circuit boards with an etch resistant pen and is printable on a RepRap. Besides the RP parts all that is needed to operate it is a rubber band which holds the pen in place.
The CAD Models are not available at RepRap but can be downloaded from Thingiverse

Pens
Fine-Tip Red Color Staedtler Lumocolor Permanent Marker 318-2
The Fine-Tip Red Color Staedtler Lumocolor Permanent Marker 318-2 is the best for this purpose.
One pen that works well on most etchants is the staedtler lumocolor permanent marker. The red color is best (the ink is also used in the marker for chemical lab glassware).
It only resists strong etchants without fail if the pen is fairly fresh, so it may be best to get the refill station so you always have a "new" pen at low cost. - via Homebrew_PCBs

We should compare this and the Fine-Tip Red Color Staedtler Lumocolor Permanent Marker 318-2. --Sebastien Bailard 22:05, 23 July 2010 (UTC)
InkJet pigment deposition
- This inkjetted pigment ink experiment resists the etchant. People are printing PCBs with Epson printers which have his DureBrite pigment ink that resists to etch acid.
Workflow:
- plot the design on PCB;
- put PCB on oven for a few minutes to dry the ink very well;
- etch the PCB.
Gerber RS274X to GCoder Converter
A little Java program to convert Gerber RS274X files, which can be exported from Eagle or KiCad, to GCode.
The code can be downloaded via subversion:
$ svn co http://ionscale.com/svn/repos/reprap/gerber2gcode $ cd gerber2gcode/src $ javac Main.java $ java Main pcb.gerber pcb.gcode Gerber RS274X to GCoder Converter for RepRap's Input: pcb.gerber Output: pcb.gcode Pen Width: 0.7 mm Offset X: 40.0 mm Offset Y: 40.0 mm Drawing Height: 1.8 mm Freemove Height: 3.8 mm GCode file generated succesfully !
This software is still in a very early stage. The pen width, offset and height parameter can be changed at the top region of the Main.java file.
