Has anyone purchased a good solution to fit 2 bigger drinks side by side in the rear cup holders? They only really fit cans.

What about designing and 3D printing? Something like

32oz. Hydro Flask car cup holder adapter by Ronn2664

This fits a 32oz. Hydro Flask bottle. 32oz. doesn't fit the cup holders in my car so I decided to design this as simple as possible for easy printing. I use ABS to print mine but PLA should work fine as well. Hope it works for you.
