About this 3D model

Intended to adapt the cup holders of a 2018 Subaru Forester to fit many metal water bottles. So far, we have found it to work with Simply Modern, Takeya, and Linus Tech Tips water bottles. it should fit any bottle that is about 3.5inches or 90mm. It is still a work in process though. The part that goes in the car's cup holder is too small. and the part that holds the bottle is too large. I would welcome any feedback if you print it.
