This is a simple adapter to fit the large 32 oz/1 L "hospital mugs" into a car cupholder.
Some gas station chains also brand these and sell them as reusable cups for the fountain soda machine.
The actual model of the mug is Whirley Drinkworks TM-32.
I made it to fit our Ford Edge, but it should work in most vehicle cup holders.
There is room below the cup for change, or other small items.
