Summary
I 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.
Improvements
After 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 hours
Speed: 3000 RPM
Airflow: 30 CFM
Considering 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.
