LifeStraw Bottle Adapter

thingiverse

I've remixed an adapter for a hose to attach to a water bladder so it can function as a gravity filter, similar to a Sawyer Squeeze or Mini. Check out this project here: https://www.thingiverse.com/thing:1271008. To secure the adapter properly onto the LifeStraw, you'll need to apply some glue. Additionally, use a washer on the other side of the hose connection, just like those used for garden hoses, to ensure a solid bond between the bottle and the filter.
