Since Zero Water has discontinued their travel cup and the smaller filters that fit it, I made this with a SureFresh 34oz container from the dollar store and a standard size Zero Water filter. The upper reservoir can hold 16oz of water and the container can also hold 16oz of water when the filter is in it. The container cover is slanted so that if the interface between the filter and the container leaks, the unfiltered water won't go into the container. The threads are meant to be a tight fit to avoid leakage. Make sure that the filter is fully tightened and seated, and it shouldn't leak. I have also provided the threaded adapter by itself so you can attach it to your own project. This is great for people who travel with a CPAP machine and need demineralized water, or of course for making clean drinking water. This was designed with TinkerCAD. Use supports for the threaded adapter and 16oz upper reservoir. No supports needed on other parts. No adhesion.
