Spout is a sprinkler head for a milk jug and the other is a pouring spout for faster water output.
Both use a straw or quarter inch ID tubing to provide air to milk jug to prevent the jug from colapsing or slurping. I print this at 99 percent for a little tighter fit and you may have to adjust for your particular printer. If you can get the tubing up into the handle it works great. Please feel free to use or modify as you need.
Milk jug threads vary and I find that my design works best with Great value distilled water jugs. Updated 10/10/2023

I printed at 99% for a tighter fit on milk jug. The sprinkler version works great in the spring on the more delicate plantings and the spout I use later in the season when I need faster water output and a longer spout to reach the pot after the plant has grown considerably. Feel free to share and modify as needed. I used a quarter inch straw or flexible tubing for the vent.
