Splicing a few files together I was able to make a Water Spout with Garden Hose Threads on it. This allows you to hook it directly to a hose and water your plants. First print tested good.
Updated to version 3: This one has fillets leading up to the thumb screw, so no need for support material. This is the version shown in the picture.
