Cup Holder Expander

Got tired of my water bottles falling within our couch cup holders. Designed these in Tinkercad to fit inside the cup holder with a shallow grip to hold my wife's Coldest bottle and my Yeti bottle while still allowing our most common cups to fit and not need to remove the expander.
These should fit most situations, but I have added the link to my Tinkercad should you need to make and edit to your own needs.
