Aerodynamic ramp - EC Fan Mount

This is a replacement funnel cover for WRIGHT1\'s Extruder Controller Fan Mount, which works to keep your MOSFETs extra cool when under heavy strain (heated build platform, anyone?). My thing is just slightly aerodynamicized (let\'s pretend that\'s a word).

Why did I make it? A. His thing deserves to be on the front page again because of how useful it is, and B. because I felt like screwing around with natural geometry in google sketchup. (not easy)
