Cup holder adapter.
The interior tapers are now flat inside, and there's a notch out of the larger section to allow for large coffee mugs to also be used in the holder.
Initial design is for the cup holder spot in a Honda CRV, which is not large enough to accommodate a Nalgene bottle. This adapter allows you to secure a Nalgene bottle in the cup holder location. I used some small round furniture pads to help secure the adapter in the vehicle location as well as a few inside the rim to hold the bottle a with a little more tension, but not so many that it gets stuck and pulls the whole assembly out when you pick it up.
