Bottle cap 25 mm

Here are two bottle caps for regular PET bottles with a 25 mm thread, e.g. the 250 ml type you see in the picture. One cap is closed and one has a pipe connector for a pipe with 6 mm inner diameter. Additionally there's a quick-connector adaptor, like in my other thing https://www.thingiverse.com/thing:2774153, so that you can attach the bottle directly to your dry-suits pee-valve for easy cleaning.
