Lost the original cap from one of the aarke bottles. The thread is abnormal, it's a double helix scattered at 180 degrees and 8mm pitch.
The sealing washer needs to be rubber or silicon, so either cut that from a sheet or print in TPU.
I do not recommend printing this is PLA, the threads strip off easily. This work well printed in PETG, ABS or ASA or PC.
Print info
The recommended print orientation is as follow.

I also iron the top layers so that the inner sealing surface is smooth.
I printed mine with a 0.4mm nozzle and 0.2mm layer height, it looks good and ensure strength.
