3D Printer Pen Mount (Configurable)

###Update #5
I managed to break my code last night and have no idea how, now everything prints mirrored and I'm reluctant to just write another function to flip the coords back. Either way it can write at an equivalent to about F5000 and produce the results in pics "Printrbot Simple Metal" which is pretty damn quick although the paper needs to be secure to avoid drift.

Code will be released out soonish.
###Update #4
Pulled together a little bit of javascript regex which converts svg to gcode and was able to draw the GNU Head quite well (see pics). Working on a function to 'color' in fill areas, probably something pattern based.
Might look at pencil wear down compensation in the future, similar to the way extrusion works in 3D printers. This idea is already on the back burner.
###Update #3
Got a chance to test it out with some a simple svg>gcode and it worked great. On a side note: always remember to turn off the extruder.
###Update #2
Just finished rewriting the original clip, the scad file isn't great but I'm sure someone who knows scad better than me can remix it.
Anyway, I think I'll stick to the V1 design for now as I'm low on filament.
If someone prints V2 let me know how it goes.
###Update #1
Just had a few moments to write a little scad which allows decent configuration. Probably breaks and I plan on fixing whatever causes breaks tonight.
V2 Looks a bit weird but I wanted it be printable without supports or anything fancy.
###Original
Simple pen mount for 40mm Fan, I just assumed the fan mount holes were spaced 40mm and later found out it was quite a bit smaller.
Will redo tonight with friendlier & cleaner scad.
Also need to make a better clip, turns out the majority of pens are not 10mm dia, mine broke quite easily.
Also plan on using the right top and bottom mounts and moving the pen clip to the same place as the hot end to increase drawing space.
