This is a remix of the Hypercube Evolution's fan duct sized for the regular Tech2C Hypercube. Shout out to both Tech2C and SCOTT_3D for their designs. I also have to give a shout out to arturslab as I used his vertical printing adaptation for this duct.
I liked the style of the Evolution's fan duct as it has a wider spread of air so I adapted it for the regular Hypercube. I also constructed a slightly steeper angle for the inside of the duct to help direct more of the air onto the printed part and off of the heat block.
I've been quite happy with the performance of this duct so far!
STL is oriented vertically as that is how this is meant to be printed. No supports or bridging necessary.
