Modified the Simonwlchan excellent shroud http://www.thingiverse.com/thing:958450  to fit with a shorter spacer for a e3dv6 hotend. Also removed some extra design elements to print a bit faster. Added a picture of the bridge-torture-test_50mm after installing this fan. Probably should lower the temperature a touch more, but it came out pretty damn great. 

With the latest changes, I shortened the length of the shroud's nozzle so it no longer hits the bed. I also widened the mouth and pointed it down. The air flow hits right below the hot end's nozzle with a wider pattern. 

You can see the new picture of the bridge-torture-test_50mm and it's improved an improvement. Again, thanks to Simonwlchan for making the original shroud this remix is based off.

Notes: No need for supports, but it can help with the inside of the shroud being smoother.
