Fan duct (radial fan)

thingiverse

It is fitting the standard i3 mega cages you can find here with the fans mounted on the inside. I have a radial fan mounted and had a printed fan duct but it was getting used. But I hadn’t the STL at hand, so I designed my own fan duct. This is the mk1, yet I am not totally confident about the air flow direction. Will take some time but I will work on it. Until now it is working good but it could be better (you know how it goes)
