Shake N Take Sports Bottle Wrench V2

My mom messed up her shoulder in a fall recently so I made this "wrench" in Tinkercad (edit it online https://www.tinkercad.com/things/5jGj7nK5IH9) to give her a little more leverage to lock the bottle into her Shake'n Take smoothie mixer. I removed the two lugs nearest the handles in the final version (as seen in the photos) as they are not needed and proved difficult to properly align. Less is better in this case! This is my first published design so I would love to hear your thoughts.
