The OpenSource EV Parts Slim Stowable Cup Holder Expander 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 two oversized supports hold bottles secure both left to right and front to back at angles nearing 90 degrees. 

We print and sell this in ASA, but ABS and PETG should work well too. We strongly suggest that you use a high-quality PETG if that is your material of choice and store it not in direct sunlight to eliminate deformation. (PLA is a no-go because of this)

This remix is designed to print without supports in most cases.

Significantly overhauled model in all ways. Bottle holder wings have gone from 3 to 2 and are wider. Different slanting to allow for printing without supports. Slightly longer and much more narrow to fit better in Rivian vehicles.
