The file 'Customizable Fan Duct System – For Quadcopters. 3D Printer Model' is (scad,stl) file type, size is 900.0KB.
This is a customizable module that I've been working on to allow you to build a propeller duct system. It is research based and should give you a noticeable improvement in duration and/or power from your system (if you can keep it fairly light and stick close to the referenced figures).
The module is for use in a ducted quad-copter that I'm designing, but as ever I like to share my modules in case it makes anyone's life easier with their designs.
If you need more details that aren't obvious in the Customizer app have a look in the .SCAD file itself - I've put a fairly serious key in about all the variables at the top of the file.
