Water Bottle Base

I made this after struggling with the new water bottles that are being manufactured. I just couldn't get them to stand on their own because they didn't have enough strength in the base to hold them up. They kept collapsing under the weight of the water. So, what better excuse to make a new 3d model did I need? This has practical purpose and is a good use case for home manufacturing. Plaease feel free to make new mixes of this design, but don't forget to allow for the same sharing of your creations. In other words, please respect the license.
