Summary This is Gascat's High performance cooling assembly originally for the wanhao i3 remixed to mount to the E3D titan aero. The only thing I changed was the mounting bracket. You will need to visit Gascat's original page to get the other pieces of this duct. (here: https://www.thingiverse.com/thing:2084339) A friend of mine was looking for a better cooling duct for his e3d titan aero, so I offered to remix this one as I am thoroughly blow away (pun intended) by the amount of air Gascat's design moves on my wanhao i3. My friend said he had to adjust the position of his cooling block for this to work, but if you are unable to do so, let me know what issues you are having and I will do my best to accommodate.
