Ender 3 S1 Pro Fan Duct / clone from stock / 5015

thingiverse

I tried some of the FAN ducts, but was never satisfied, so drew one myself. The Fusion360 file is attached. The FAN duct is as close to the original as possible, but has a little more distance to the hotbed. The design has no corners, so the air can blow straight from the blower-5015 to the nozzle. The air from the blower is taken from the hotbed as in the original, i.e. the air is not too cold. I have printed the design in carbon/nylon with support. update: added version 5, same design just a cleanup and a lot more stiffer so higher speeds are possible with sonic pad update: added v6, i added an air-channel to suck the air from more below the extruder So you need a 4xM3 screws, 1xM3 nut, possibly a few washers, a 5015 Blower 24V, I took the one from Winsinn (there are on Amazon, as well as the screws, I bought a set with different sizes here).
