Hot-swap Pen Holder

thingiverse

I saw Tech2C's video about drawing on a 3D printer recently and thought I would give it a try. I was toying with the idea of pausing the print and using different colored pens to give a cooler effect so I designed this drop-in replacement for the e3Dv6 hotend that would allow hot-swaps between pen cartridges during a printer pause. It will hold cartridges from the Pilot G-2 series ballpoint pens and should be at the right height so that you don't have to adjust the limit switches on your machine at all. I'm still working out how to pause the print at different parts in the gcode, so once I figure it out I'll put up a tutorial. Feel free to contact me if you know how to do this without pausing between layers since that doesn't seem to work.
