Simple caps for a bottles sold by Decathlon (500 ml). There is one model for the PCTG bottle and another one (larger) for the aluminum bottle.

I put many top layers (7) to ensure it is perfectly tight, and several walls (4) for stiffness / rigidity of the threaded part.

You will need the original silicon join (or print one yourself with extra-soft TPU)
