NEW APPROACH FOR THE HEXAGON HOT END SHROUD
Finally came up with my own shroud design for the hexagon hot end that should do a better cooling job than the stock shroud, and shouldn't have a tendency to melt and drip onto the print bed or a print. See http://www.thingiverse.com/thing:693913 for STL files. Two styles are provided - both use a 25mm fan like the 3CFM Sunon MAGlev MC25101V2-000U-A99 fan. One style mounts the fan flush to the shroud, and the other style angles the fan exhaust upwards by 10 degrees to clear the heated bed area.
