This bottle coupler fits the latest fizzy drink thread standard: PCO-1881, which can be found at https://www.bevtech.org/threadspecs-downloads.asp.
It is designed to fit:
2 x BS1806 #215 O-rings.
which have the following dimensions:
CS: 3.53 mm
ID: 26.57 mm
OD: 33.63 mm
I made this to join pairs of 2L fizzy drinks bottles for my son's water rocket.
It is emblazoned with "Rocket Boy".
Print instructions
I recommend printing this in PETG or ABS for a tough, strong part.
