This is a customizer to generate funnels parametrically.

Version 8.7 available. Now the funnels can have an offset and/or angled spout for hard-to-reach filling jobs. And there are so many other funnel-like things you can design!

Although it is a remix (thanks Salvador Richter), it expands the original project substantially.

To all those who send me $ tips: thank you so much! It's really rewarding to know that my work is useful to you and appreciated.

Customize the funnel with the following parameters:

Size and shape

• diameters: external diameters at three locations (top, middle, bottom);
• overall height;
• wall thickness;
• neck ratio: the higher the parameter the longer the "neck" of the funnel. At 1, the neck is one half the overall length, at 3 the neck is 5/6 of the overall length;
• squish ratio: sometimes you need funnel with a "squished" elliptical section. (if >1, the "diameters" are the major axes of the ellipse);
• offset spout: moves the spout from the center to the edge of the funnel.
• angled spout: angles the spout away from the handle for hard to reach filling holes (automatically creates an offset spout);

Optional features

• handle length: generates a handle if this parameter is not zero, the larger the parameter, the longer the vertical portion of the handle;
• handle overhang: if a handle is generated, the larger the overhang, the longer the horizontal portion of the handle;
• handle angular position: useful for offset spouts, choose if you want the handle opposite the spout, on the spout side, or on either side of the funnel.
• add vent: generates supports that allows air to escape around the neck;
• vent projection: make the vent ribs more or less prominent.
• high wall: if selected, the well of the funnel has a steep cylindrical section before narrowing;
• slanted tip: cuts the tip at a 35degree angle.
