Aquatainer Dust Cap

This is my first attempt at making a dust cap for my aquatainer. Its a snug fit and has a leash to prevent accidental loss. I used a strand from some 550 cord / paracord.

That said, I havent tested this for extended use so i cant say exactly how this will work, long term.

PLA+ isnt the best filament to use but its what i've got. ABS will be a better option however.
