Sawyer Squeeze Hiking Water Filter Adapter

This is a connector to join a water bottle to the output of a Sawyer Squeeze water filter.

See Squeeze Water Filtration System for details.

This model has a standard 28mm thread, so it will fit the majority of store bought PET bottles, as well as the output thread of the Sawyer Squeeze filter.

This can be used in two ways:

• To connect a full bottle of clean water to the output of the filter, so the filter can be cleaned by back-flushing.
• By connecting an empty bottle to the output, and a bladder, full of dirty water, to to input to make a gravity filter.

See here for how to use this filtering method

I've designed this in OpenScad - files included. I use the Spiral-Extrude library (included here) for the thread.
