Sawyer Squeeze to Wide Mouth Nalgene Threaded Adapter

#Summary
This part allows you to thread a wide mouth Nalgene bottle to a Sawyer squeeze filter's clean end, so you can gravity filter by hanging the entire assembly off something. I used this on a week long backcountry canoe trip and it served me well.

#Printing
I used PLA with 20% infill, 0.2mm layer height and no supports. Worked on the first try.

###Update - Apr 2022
Big thanks to tkamp for bringing to my attention that the air escape vent in the design was not placed correctly. This has been fixed in the newest design. It was also noted that the part might need to be scaled up 1mm in both x and y directions in your slicer - this was not needed in my case but might be helpful for you (although I recommend printing in the default size first).

Thank you to walter and kludgemonkey for generously sharing the solid files for their designs. Grafting them together was all that I did. Without their models, especially the well-designed threads, this project would have been extremely difficult. I have but stood on the shoulder of giants.
