This is a fully adjustable mount for the Cartographer probe on the front of the E3NG toolhead.

It allows for up/down adjustment as well as rotational adjustment to help ensue it's level to the bed.

Put 1 3mm heatset insert into Carto-Mount-Cowbite1.stl and just put a short 3mm bolt through both parts.

Then use slightly longer bolts for the lower toolhead mounts to go through the mount and the duct.
