Twin bottle cap - with cutouts for o-rings.

Tried original version, which worked great but was not really suitable for liquids. This is my humble attempt to fix that.

Initial dimensions based on jebissey's twin bottle cap design (https://www.thingiverse.com/thing:5482037). After that I re-did the cap pretty much from scratch (e.g. more pronounced threads).
