This is a Head for a Prusa i3 Hephestos that fits a E3Dv6 with Bowden and a Induction Sensor for auto bed leveling on the smallest space possible. The induction sensor is spring loaded on a screw which allows adjusting it without having to remout it or fiddle with the nuts they come with it. The fan duct fits on a "standart" blower fan, and directs the air directly underneath the nozzle, within 1-2 mm, from both sides, left and right of the hotend. Any feedback for improvements is welcome!All screws used are M3. Should be straight forward to assemble. Tollerances for the hotend are quite tight and you will have to file a little bit to get a perfect 100% fit. Kept it that way so that there is no play in the hotend.
