Hero Me Ender 3 Plotter

This is a remix of Pen Holder by pascalmakes, but for Hero Me mod on the extruder.
I replace Hero Me ABL attachment with pascalmakes's pen holder.

As for how to create obj for 2d plotter - you can see it on https://www.youtube.com/watch?v=CuWZWAfBsm8

You will need to modify Marlin to enable `ARC_SUPPORT`
