Applicator Tip for Caulking Gun

My quick take on a commercial product that no longer seems to be available.

You can customize the radius of the bead and the diameter of the opening by changing the values of beadrad and opendia and regenerating the .stl file.

The large end of the opening tends to sag during printing, but it does still work. I could keep the differenced-out portions of the "wings" so that I could print it on end instead of flat, but don't have the inclination at the moment... .

This might be even more effective if printed in flexible plastic, but I don't have any and have never tried any, so I can't say for certain.
