Adjustable height E3D V6 nozzle seat for dual nozzle 3D printers

Adjusting the nozzle height on some dual nozzle printer rely solely on the accuracy of the components. One such printer is the German RepRap X400. There is no easy way of setting both nozzle's height correctly.

This nozzle seat solves this problem with a linear cam height adjustment mechanism embedded inside the nozzle's clamp. This clamp aligns the nozzle with the MK8 hobbed gear. Together with the push lever, this is a revised extruder for the X400, but will work with most direct drive extr
