Ender 3 S1 Fan Duct for stock Fan

cults3d

This is a Fan Duct for the stock Ender 3 S1 Fan. Since -in my opinion- the stock Ender 3 S1 Fan isn't as bad as some say, I designed a Fan Duct which directs the air to both sides of the print in order to reduce warping and get a more uniform cooling on your prints. The fan duct has a good, uniform static pressure and flow which is directed below the nozzle onto your prints. Mounting: 1. take off the touch-probe by unscrewing the 2 screws on top of the probe 2. unscrew all 3 screws of the fan mounting shroud 3. unscrew the 2 screws at the front of the fan. 4. clamp in the fan duct in the exit-opening on the fan 5. screw in the 2 long screws through your fan duct into the fan again 6. adjust the shround in a way the fan duct doesn't touch the build plate 7. mount everything back up NOTE: The fan shroud has some up/down play within its mounting points which gives you some room for adjustability in terms of up/down tilt on your fan duct!
