A nozzle for attaching to a 3-liter "Ocean Spray" brand juice jug. I made this for my wife to help her in watering houseplants.

It's important for the collar part to have good layer adhesion. Otherwise, the collar might break when you tighten it over the nozzle. I used PETG with the hot end at 250 and the fan at 15%, and the part seems to go together OK.

The parts in the photo have tiny blobs which indicates the filament may have taken on moisture. .

It was a little tricky to reverse engineer the screw threads from the juice jug. The threads are triple start, and the rolled edges on the mouth of the jug made getting good measurements a challenge. I had to go through several iterations before arriving at an acceptable solution.

The nozzle portion required fixing with Meshmixer to make it into a proper manifold.
