This E3D V6 mount will keep the original nozzle location of the A8. It has a provisions for a M18 sensor with locations of X 33, Y -5. I am using M4x20 socket head cap screws to mount it, I also had to tap the bearing blocks all the way through. There are several fan ducts on the site that can be used. I had to make a change to the mount because the M18 sensor mount was to high and to close to the back wall to allow for the star washer. Sorry if anyone printed it before the change. If any one would like some minor changes let me know.
