Aquila X3 direct drive mount, with filament sensor. For dual extruder, no loss of X axis.

Remix of https://www.thingiverse.com/thing:4930478. Adjusted to fit dual gear metal extruder with no bend in the filament tube and mount for filament runout sensor. you may need longer screws for the sensor and a couple of pieces of Bowden tube as spacers. 

This is a work in progress. It is working great on my X3 but needs refining. 

Tweaked sensor mount, shroud fixing and right carrier bolt grip for better stability under fast retraction. Added embossing.
