Pen Plotter Head Creality Ender Series

This is a HUGELY improved design compared to my last design.
Print Pen Holder New UP and Pentonic Holder twice.
It requires 2x M3 and 6x M4 Screws and 4x M4 nuts.
M3 screws will go in the backplate to hold it with x carriage.
Assemble it as shown in the image.
Pentonic holder has an internal diameter of 8.8mm, use it to hold pencils and thin pens in the center. If you want to hold thicker pens or markers, just remove the pentonic holder and mount the pen/marker directly.

NOTE:
Don't forget to change these settings (mine in CURA) so that little spring-like action of the pen can be done in the vertical direction.
1) Select "Fill gaps between walls" to nowhere.
2) Keep "Filter out tiny gaps" checked.

Also, your machine needs tight tolerances to assemble pentonic holder with penholder new up. so make sure it is calibrated. Using support is necessary.
