Big Gulp Cupholder Adapter

This is a cupholder adapter designed to fit the 7-Eleven Big Gulp reusable cups. It was made specifically to fit the cupholder in a Dodge Dakota, but may work with other vehicles too. The outer diameter is 90 mm, and the inner diameter is 78 mm. It is 55 mm tall from the base to the rim. I've included a hole in the center, as the person I designed this for wanted to screw it in permanently. I printed it in PETG-CF to hold up to the temperatures a vehicle's interior can experience. Print away if this is useful to you, and let me know how it turns out!
