Printables link. Apologies for the... very lazy select + background blur. In the land of windows I would have used paint.net, but I'm coming to you from a mac today and haven't found a great alternative.

    I loled. It's a tornado adapter for a pair of Gatorade bottles. These were pretty popular when I was the age my kids are now, granted they were for 2L soda bottles.

    How does this one compare? I remember the 2L ones.

    Now I'm curious how the tornado changes with different size / shape bottles

    It workes pretty well. Most of the injection molded vortex generators have an oreface that restricts flow, so I incorporated that concept into this design.

    The only downside is fluid capacity.
