openscad funnel script makes funnels with 2mm thick wall.
$fn=100;
difference() { //creates the wide top of the funnel
cylinder(d1=50,d2=12,h=40);
cylinder(d1=46,d2=8,h=40);
} // end difference
difference(){ //creates the spout
translate ([0,0,40]) cylinder(d1=12,d2=12, h=30);
translate ([0,0,40]) cylinder(d1=8,d2=8, h=30);
} // end difference
change the cylinder diameters, heights, wall thicknesses and translates for variables and that one script will generate any size funnel you like. I can't be arsed to do it now :-)
Change the d2's in the spout section to get a tapered spout. Don't forget to change the internal diameter as well :-)
funnel will print the way up it's generated, with a 2mm wall you can make a pretty steep sided funnel.

wow talk about paranoid:
Another issue would be the dangers from extruder nozzles. If the nozzle is made of brass, then lead might leach into the print.

It's certainly true. There is special waste handling requirements when dealing with coolants/cutting oils from shops that machine brass.
I doubt it would be significant from a 3d printer nozzle.

I hesitate to write about this. I do not intend to blow my own trumpet.
As someone wrote previously, PP is the best material for your purpose. But PP filament has the issue, big CTE. We, NANODAX , has announced glass wool filled PP filament which is really usable.
- Surface is very smooth.
- Easy to cut, shave the model.
- Has flexibility and strength.
- Water tight wall.
- Light.
- No odor during process.
- Endure 120-130 degree.
- Chemical resistance
- Parameter tolerance is large
This link to Z-temp forum is good to understand how it behave.
The filament is going to be put into market end of SEP if everything goes well.

Practically, do you know how much the nylon will degrade and over what timespan?
