Prusa i3 MK8 extruder attachment

The attached is a couple of parts I have modified from others.
The blower I have added two 5mm LED holders, So it lights up the nozzle and work piece.
The extruder carrier, started out as a self contained unit that had bearing holders built in, but I found another bearing holder which was much more suitable (thanks toolson,) http://www.thingiverse.com/thing:1036871
I wanted to experiment swapping jobs between an MK8 and Bowden, so I used "toolson's" base and Bowden, and added this MK8 to pic
