The picture shows two printed nozzles and the original. The tall narrower one causes too much back pressure and doesn't work well so it is excluded from the STLs. But I have included a base by itself so you can make a nozzle of whatever shape you want.
Requires a small magnet be glued to inside the nozzle to properly attach to the duster. The shape of the pad for the magnet will accommodate a small round, oval, or rectangular magnet.
