This funnel is designed for fast pouring without splashes. The bulge on the wall aids in guiding and swirling the liquid, creating a vortex. When placed on a round opening, these bulges enable air to escape from the outside, preventing bubbling in the funnel.

Printing: 
There are two designs available: one with a round outlet and another with bulges, both having a diameter of 10 mm. Adjust the funnel's scale to your preference before printing; the 3mf file is already set to 200%. Print in vase mode, with the outer wall thickness set to 0.7-1 mm. For pouring hot liquids, it is recommended to print the funnel in PETG or ABS.
