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.

-Finally, this plotter is made to use the zeroing that has already been performed with the hotend. This means that if the printer is already zeroed, no extra work is required! Remember to program a lift of 1-2mm for parts of the plot that will not have pen contacting the paper.

Note: If your pen cartridge seems too loose or tight in the plotter, flip the tensioning nut around. It is designed to be hollow on one end so that maximum adjustability can be achieved.
