The Ultimate Pen Plotter for Ender 3

Why is this the "Ultimate" Pen Plotter for the Ender 3?

Well, given that Thingiverse already has plenty of Printer-Plotter conversions, this one adds some unique features that not many others have.

-This holder is designed to print with none or little supports, if they are required the only part that should need them is the tensioner screw.

-There are curently no other plotter tools that hold the pen cartridge rather than the pen itself. This brings a lot of advantages, such as easy mid-print color changing, as well as greater versatility in possible pens used. Most other plotters on thingiverse do not allow a precise enough way of replacing new colors of pen mid-print and may require re-zeroing.

-This plotter incorporates the spring that already comes with most 'clickable' pens as a buffer to allow softer drawing of the paper, as well as easier zeroing with the paper/bed.

-Speaking of zeroing, this plotter is compatable with the CR touch stock mount for Ender 3.
