Soda bottle watering cap

thingiverse

I spotted a dad rinsing off a kid with a drinking bottle. It didn't look very efficient, so I came up with a shower head for any standard plastic bottle! It works really well. Update 23.7: I made a smaller version of the cap that gives a much lower flow rate. This means that after swimming in the ocean, a person with short hair can rinse off seawater using less than half a liter of water! This new cap is called "3Dan_soda_waterer_small_flow.stl". The updated version has a V-shaped surface that touches the bottle and acts as a seal. A little bit of water still leaks from the threads, but I don't see it as an issue.
