Soda bottle watering cap

I saw a dad showering a kid from a drinking bottle. It did not look so practical. So i made a shower head to any standard plastic bottle! It works nicely.

Update 23.7:
I did a little bit smaller version of the cap. This one gives a much lower flow. This means that after swimming in the sea a short haired person can shower off the seawater with less than 0,5l water!
This new cap is named "3Dan_soda_waterer_small_flow.stl"

The newer version has also a V-shaped bottle contact surface which functions as a seal. A little bit of water is still leaking from the threads but I do not see it as a problem.

Please see an awesomeGIF animation of the product in use!

Update 4.7.20:
User "kickformoney" discovered that a G20 20x3 mm O-ring fits in the cap and seal it completely. Nice find!

Notes:

I printed the part in the pictures in ABS+. It turned out nicely. I used 0,1 mm resolution to get the threada as good as possible. 0,2 mm is fine also. The water holes are 1,5mm in diameter.

How I Designed This

I found the cap thread here at thingiverse. Then i built the watering part on that part.rnrnDesignes in Fusion360 and printed with Simplify3D
