About this 3D model

Water bottle holder adapter that fits in your car's cupholder. Fits my 16oz thermo-flask perfectly and makes it easy to take it out without the rubber boot coming off every time. Works great for thinner flasks as well. Regular sized water bottles might end up getting caught in the adapter when you go and take it out however. Also, I am under the assumption that car cup holders are all or relatively close to the same dimensions.
