Semi Circular Fan Duct for E3D V6 Direct Drive

thingiverse

I swapped my stock hot end for a E3D V6 using the carriage from Cobratronics. I had been using Lokster's semi circular fan duct on my stock setup and liked it, and wanted to use it on the new setup as well but it didn't fit. I fired up Tinkercad and made some adjustments! lol I used a remix of his original design that has a little smoother surface than the original. It's not perfect by any means, I just quickly cut his duct, move the two halves so the fit the fan and fit around the heater block, then filled in the gap. I cleaned up the edges a little bit but didn't take to time to get everything exactly perfect. It prints fine though, and the little imperfections are generally not even small enough to see once it's printed. ;) With it being longer and offset a little, I found it didn't feel as secure as the stock one did, so I ended up drilling a small hole where the duct overlaps the fan (through the duct and fan) and securing it with a small self tapping screw. It give me a little extra piece of mind not worrying about it falling off during a print. I printed it as you see in the picture, sitting down on the bed in it's normal orientation with no supports.
