Dopper water bottle Car holder adapter

Adapter to fit the Dopper water bottle in my car drink holder, Outside diameter is 10mm larger then a Soda can so should be a snug fit.

This is my first concept design I quickly made in sketchup to check dimensions. When I find a comfortable size for easy daily usage I'll make a pretty one. (now in daily commute testing fase)
