Mounting Plate for 2 in 1 out Switch Hotend for Geeetech Prusa I3

Update 12/6/17 I AM PLANNING ON CHANGING THE COOLING SCHEME FROM AN AXIAL FAN TO A RADIAL FAN. I ADDED THE FIRST CUT AT THE DUCT AND A TEMPORARY TRANSITION PIECE USING A 30 MM AXIAL FAN . THE DUCT MOUNTS ON THE BACK, NEAREST THE LINEAR BEARINGS, SO IT DOESN'T INTERFERE WITH THE LAYER FAN AND MAKES IT EASY TO CHANGE HOT-ENDS. I HAVEN'T TRIED IT YET, AND IT MAY BE IN-PROCESS FOR SEVERAL MONTHS. PLS LET ME KNOW IF YOU TRY THIS AND HAVE ANY SUGGESTIONS.
