Improved Wind guide for turbine

SummaryI was not completely happy with my previous wind guide turbine so I decided to improve it even more. Now it is lighter, easier to print and fits like a glove.ImprovementsAfter about thirteen versions I think the final version is quite good. The fit should be perfect for most of the 12V turbines like this one http://ebay.to/1SCr1Hk Detailed view Compared to the original wind guide of my Prusa i3 kit, this improved part is more than 10% lighter. Old part that came with the Prusa i3 kit Lip to prevent air leaks and middle rib to add rigidity and make the part even easier to print Performance From the datasheet, the traditional turbine fan has the following properties:Life Expectancy at 40 Celsius degree: 40000 hoursSpeed: 3000 RPMAirflow: 30 CFMConsidering the output of the fan the maximum expected airflow is about 60-70 m/s. With that we can see the internal behavior of this wind guide.
