My Reduce water bottle lid broke in a couple places so I designed this replacement. This does not include the flip top and I moved the straw hole to the edge rather than in the middle like the original. I tried to print this upside down but the supports made for a rough finish on the top so I would recommend printing this with the top up and have supports on the underside.
This replaces the Reduce large lid and should work with the 30-50 oz. tumblers, I have only tested with the 40 oz. though since that is all I have.
The author marked this model as their own original creation.
