Because my waterer was broken after some weeks I redesigned my own version of it.

Use layer hight ≤0,2mm because of the thread.

With the hook you can hang it for horizontal alignment. I found that the hooks glues perfect with some silicone. Don´t use a hot glue, it wil fell of after some cold nights! The hook is printed laying on the side. 

Fits perfect for 1,5l PET bottles.
