-old- Mostly Printed CNC -Add On- Drag knife/Pen mount

Easy little print to add a drag knife for paper and vinyl, or just a pen holder to test you gcode.

I use a liyu style knife holder. Grab one on ebay for $7-$15. Liyu pen holders as well, $5-$10

Drag knives have a blade offset. So sharp corners will be a bit wrong, your files should all have at least .2mm rounded corners to fix this issue.

Per Mike G's (http://www.thingiverse.com/coolreactions/about) Suggestion I have added a tool holder that fits in the standard tool mount if you have it mounted low enough. Thanks Mike
