Semi Circular Fan Duct for E3D V6 Direct Drive

thingiverse

I swapped my stock hot end for an E3D V6 using Cobratronics' carriage. I had been using Lokster's semi-circular fan duct on my old setup and liked it, so I wanted to use it on the new one too, but it didn't fit. I fired up Tinkercad and made some adjustments! I used a remix of his original design with a smoother surface than the original. It's not perfect, but I quickly cut his duct, moved the two halves to fit the fan and heater block, then filled in the gap. I cleaned up the edges a bit but didn't take time to get everything exactly right. It prints fine though, and the small imperfections aren't even noticeable once it's printed. With it being longer and offset slightly, I found it didn't feel as secure as the stock one did, so I drilled a small hole where the duct overlaps the fan and secured it with a self-tapping screw. This gives me a bit more peace of mind knowing it won't fall off during a print. I printed it just like in the picture, sitting on the bed in its normal orientation without supports.
