About this 3D model

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! Source also available at https://github.com/spinorkit/FanDuctOpenSCAD Inspired by http://www.thingiverse.com/thing:63123 Uses: http://www.thingiverse.com/thing:18273, thanks doommeister, and http://svn.clifford.at/openscad/trunk/libraries/shapes.scad, thanks Catarina Mota. 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.
