About this 3D model

This is an Inkscape extension modified from Makerbot's wonderful Unicorn G-Code extension. Instead of using the servo based pen control this uses the Z-axis along with the spacer replacement pen holder I modified here: http://www.thingiverse.com/thing:15788 Or this one here: (or any number of other pen holders) http://www.thingiverse.com/thing:16901 I will create a revised pen holder that will eventually center the pen so the plot will be centered once again. I take no credit for the original code was all done by Marty McGuire - see the original thing for all the details.
