Sawyer Squeeze Adaptor for Evian bottles

thingiverse

This is an adaptor to allow the use of Evian (and other still water) bottles with the Sawyer squeeze and sawyer squeeze mini. An internal baffle was added during protyping in order to ensure a good connection to the Evian bottle - this prevents any unwanted leaks of dirty water whilst filtering. This means that the design works well with PLA. However, if you print with TPU then you find that the internal washer in the sawyer squeeze (which everyone loses!) is no longer required. So this design, when printed in TPU, provides an excellent solution to the issues with missing washers in Sawyer Squeeze filters.
