Pen plotter - draw on paper or create pcbs Zonestar p802 (v2)

This is a pen holder I made quickly in Fusion 360. It holds pens with ~10mm diameter and is installed instead of the proximity sensor on the right side of the extruder. This allows for fast switching between regular printing and pen holder mode. You can use it to create pcbs by using a marker to draw on the areas that should be copper after etching. Alternatively you can just use paper to test it.

The screw and nut are m3.

Recommended settings to use in your slicer:
- z-hop/z-lift: 1-2mm
