Great design! Thanks. I went down to the local hardware store and found the largest rubber o-ring (#110 - whatever that means lol) and this one is just barely too small. Look at my picture and you notice the o-ring doesn't quite fit down into the groove. But, it works perfectly.
Thanks once again!

What thread type you using ?

Cool design! does this work with a certain size rubber o-ring?

How much clearance did you allow between the male and female threads? Trying to make a different model with a screw thread - initially tried an ACME thread but it didn't print very well so this conventional (metric) thread looks more printable

printed a few at 60% scale with the cap at 60.3% scale with 35% infill and it works beautifully and they are STRONG! amazing design.

This will make a good geocache. Nice.

I added a new bottle top with a hole. Sorry, but the new one is on one of the vertices and gives more meat to the 550 cord.

I added an new top with a hole suitable for 550 cord. This can be used to attach the container to you canoe, kayak, or pack. For anyone wanting to make this I design the file with the idea of using no support structure, including the top version with the hole. Enjoy!
