Pen Plotter adapter for Hero Me Gen7

Edit: added a V2 version with a taller pen-holding section which removes wobbles almost completely. Massively improves quality of drawings on my tests.

Wanted to try out some pen plotting on my printer running a Hero Me Gen7.2 setup, so I found what seemed to be a nice pen holder and made it compatible with it!

The holder has a standard ABL connector, so any ABL wing that attaches to the left of the Hero Me base works in theory. Since the pen is stuck in place with an m3 bolt, putting the adapter on the left side is necessary, to be able to loosen/tighten the bolt when setting the pen height.

You will need Hero Me compatible heatset inserts, as well as two M3 bolts (one to fix the pen holder to the mount, and another to fix the pen in place) and an m3 nut.

In my case  I used the HMG7 BL-CR Touch Compact Left Wing in order to not interfere with my 5015 fan.

Print the adapter as is, no supports needed. Remove the built-in supports on the lower section afterwards
