This is small piece will make your life easier! (when it comes to use your pen plotter)

I created a replica of the servo lifter used in the original Axidraw, to be used with the 4xidraw https://www.thingiverse.com/thing:1444216 pen plotter or other similar 2D plotters.

This piece should be attached to the servo with the small screw it usually comes with, or it can be glued instead.
