Fan-Duct for Prusa Mini (Carriage)

This is the remix based on a carriage made by okrauskopf. I wanted the air to be split evenly into three cooling sides which was not possible with the original model.

With this modification sides of the models, and bridges are better cooled. Additionally, I do not have any problems with heatbed collisions at all, which is often with other modifications. I printed it with 50% infill, for better rigidity, but 20% should also be ok (5-7 gram difference depending on the used filament. I printed mine with PETG HT100 from Spectrum). 

Thanks for the base model which is a great upgrade over the original design.
