All other creator's part cooling ducts for the creality Efit extruder did not work with the Spider hotend I installed (the nozzle wasn't aligned.) I remixed a design from @DCHFPV for the Sprite extruder to fit the stock fan from the E fit.

I have successfully printed at speeds of ~250mm/s & acceleration above 5000mm/s^2 on my ender 3 using this part cooling duct. (minimal upgrades, running klipper)

If this works with other models of extruder, hot end & part cooling fan, please leave a comment letting me know. original model: https://www.printables.com/model/273619-creality-ender-3-s1-spritepro-extruder-part-coolin
