This is an alternative nozzle for a Turbo Fan/Jet Fan, featuring much higher nozzle pressure than the stock version.
In my opinion, it offers the perfect balance between pressure and airflow.
There's a small notch on one side, which should face up to align with the openings on the fan.
Developed and tested on the ZBESYQ X3 (product markings), also known as the CAER Mini 3 Gear (product listing).

The base of the nozzle is 38.6mm wide. As the first step in verifying compatibility, measure the size of your fan's baseplate.
IMPORTANT: This model requires the insertion of a 10x3 mm magnet. It’s possible to use a magnet with a diameter of up to 15 mm. Use the OnShape link below to adjust the "Sketch 5" drawing for the diameter and "Extrude 4" for the height.
Feel free to adapt my design to your model or preferred magnet dimension:
