OpenSCAD source code for a supportless, parameterized fan duct that is currently configured to fit an E3D v5 hot end and a Prusa i3 reworked Wades extruder from http://www.thingiverse.com/thing:119616.
Please bear in mind this is my first OpenSCAD program, and the first 3D object I have designed using any sort of CAD software, so there will be scope for improvement!

Print without support in ABS.
Before printing, set, at least, the parameter to the value you use for printing.
Update: added the file FanductOvalJHead45.stl, which is configured for a J-Head with a vertical distance of 45mm from the bed to the center of the mounting bolt.
Update: added the files FanductOvalE3dv6PrusaReworkv4.stl and FanductOvalE3dv6.scad for the E3D v6 . This stl should be printed with 0.2 mm layer height.
Measure the mountToHotEndBottomZ parameter (in mm) by homing the z axis and measuring the vertical distance from the bed to the center of the mounting hinge, as shown in the photo.
Also measure the mountToFilamentHoriz parameter as shown in the photo to ensure the vents will be positioned symmetrically around the nozzle.
Print in ABS without support.
I used Cura with 0.4 nozzle, 0.25 layer height, 0.8 shell thickness,0.75 bottom/top thickness, 20% fill, bed temp 110, and brim platform adhesion.
For the E3D v6 version, use 0.2 layer height.
