Summary EXPERIMENTAL!!! Print at your own risk. This is still a work in progress, I'm about to start test prints soon. X Carriage to use with the stock bearing/bushings for use with E3Dv6 clone and Titan clone in a direct drive setup with an arm to hold a BLTouch sensor. Part cooling fan should be mounted on the inside of the arms not the outside - theoretically to line up correctly with the hotend.
