Simple Funnel 3D Models and STL Files

The models differ mainly in how air escapes and how the shape is built. Vented funnels add a separate channel or notch so liquid flows without gurgling, while parametric versions let you change the top diameter, the neck and the wall thickness before exporting. Some designs are made for vase mode, which means a single continuous wall and no internal supports; others are split into a cone and a spout that you join.

When choosing, look at the neck diameter and compare it with the opening you want to fill, then check the overall height and the wall thickness the author lists. On the model page, read whether supports are needed, which material and layer height were used, and whether the author shows photos of real prints. A thin wall prints faster but flexes; a thicker one holds its shape and takes longer.

To narrow the results, try words that describe the job rather than the object: bottle filler, powder scoop, oil funnel, or airbrush filter. Adding a size, an angle or a feature such as vented, angled or parametric usually cuts the list quickly. Related topics like funnels for filament waste, plant watering or kitchen use lead to the same kind of geometry with a different neck.

If the fit matters, print a short test of the neck first or scale the model in the slicer by a few percent. Funnels that sit on a bottle benefit from a slightly wider seat, and ones used with powders work better with a steeper cone. Check the author's notes on material, since some filaments tolerate warm liquids and others do not.
