Applicator Tip for Caulking Gun

thingiverse

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. Instructions I loaded the .stl into Reptier-Host, rotated it by 90 degrees around X, then used the "lay flat" function to make sure it was properly oriented. The opening goes towards the corner of the surfaces you're caulking; pull toward you while extruding caulk with the gun at an angle of between 45 and 90 degrees. You'll get the hang of it pretty quickly.
