Part Cooling duct mod for Prusa i3 Mk2

thingiverse

On some of my most intricate 3D print designs, I've discovered that the standard Prusa part cooling duct, which blows air solely from the front, is insufficient. Steep overhangs and fine details on the backside of the build plate seem to struggle as a result. Since Ultimaker employs two fans blowing from opposite directions, I thought it would be worth exploring what could be done for the Prusa. Given the limited space available, my only feasible option was to modify the stock part cooling duct. My adaptation not only blows air on the print from the front but also from the side, and this appears to have a positive impact on more intricate prints.\r\nhttps://youtu.be/qhA5XOsIb3c
