Ender 3 360° Stock Fan Nozzle

thingiverse

360 degree bladeless fan nozzle designed specifically for Ender 3 stock fans. I've successfully used it with a silicone sock on the hotend; I'm not sure if the standard insulation will be sufficient to prevent the nozzle from melting. Printing it in ABS would offer even better results. You may need to experiment with non-uniform scaling to ensure that the center of the ring aligns perfectly with the nozzle while remaining horizontal, as this can vary from user to user. This setup has delivered the best overhang performance I've achieved using the stock fan, but any further improvement will likely require a fan upgrade. If anyone is willing to test my design, they are more than welcome to use my assets.
