Mutoh XP Series Ball Point Plotter Pen

This is an old style longer body plotter pen which can be used in Mutoh XP series, Gerber Embosstrack or Fas track, and possibly other Plotters.

Modify a ball point pen by using two ball point pen springs, and cutting the ball point stem short enough to fit within the 'reservoir'. You may also need to stretch and/or cut the springs.

On these plotters, the head uses an optical encoding system to identify the tool. I replicated this by printing the tool in black, and then using chrome tape. The tool shown here is tool #3. You can search for their specific identification marks to designate it for other locations within the plotter carousel.

The cap (if printed) should be printed in TPU/Flexible. Not sure it would work/fit if printed in PLA. The Tip and Reservoir Screw together, holding the pen in place using internal stops for the two springs.
