The OpenSourceEV Parts Slim Stowable Cup Holder Expander V2 for the Rivian R1S and R1T is the easiest, most functional way to hold oversized beverages in your vehicle. It adapts the stock 3.2" cupholder to a 3.66" cupholder -- this fits common containers such as the Nalgene 32oz and 40oz, and the Hydro Flask 32oz and 40oz bottles.

There is a Rivian-specific feature that make it better than more general products that do the same thing -- it's slimmed down sides. Because it's thoughtfully shaved down, it stores easily in a door pocket when not in use. (both in the front and rear doors) Additionally, it allows two of these to be positioned side by side in both the front and rear cupholders, and for bottles to be installed without deflection. 

The new, Version 2 of this product further shaves down the sides to allow the door pockets to close more fully when stored. It also has an overhauled construction model to be more durable, and is less expensive.

The two oversized supports hold bottles secure both left to right and front to back at angles nearing 90 degrees. These are constructed out of ASA for superior durability, UV resistance, and temperature handling of up to 300 degrees Fahrenheit. 

Bottles not included. Priced each.

This product is a significantly reworked version of the "Car Cup Holder Bottle Adapter" created by @roblpetty on Printables, located here.
