Building an all ABS extruder mount compatible with the E3D hotend

Part 1: Extruder mount (works with Greg's accessible extruder)

This is a description of an extruder mount I designed and constructed that is compatible with the E3D hotend. Since the E3D uses fan cooling, it is often imperative to prevent this cooling air from blowing down onto the heated bed during the print, as this can cool the bed surface and thereby lead to warping of the part, particularly during the first few layers of printing. To solve this problem, the extruder mount was designed to fit snugly with the exit of the fan shroud, directing the air into a chamber with holes that direct the air sideways or upwards away from the bed. This mount is designed to fit onto the X-carriage of a Prusa-i3 type printer, and fits Greg's accessible extruder.

Part2: E3D mounting Plate

In order to hold the E3D hotend in position, a mounting plate is required. This one is designed out of ABS. It has two mounting holes for 8-32 screws. The part is shown below.

This E3D mounting plate, designed for the Tubularbot3D printer. Is also compatible with other Prusa i3 printers. This design allows the top of the E3D hotend to mate directly to the bottom of Greg's accessible extruder.
