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. 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.

Great concept but not quite there

Description makes it sound like it fits in the side pocket. Technically it does with the pocket expanded and protruding out. Stays attached to the bottle and pulls out of the cup holder. Somewhat defeats the idea.

Broken

Love the fit and idea. Printed plastic however broke after two weeks of use

Hi Lawrence - Thanks for the feedback. We'll look into ways to beef up the construction. In the meantime, please reach out to us so we can get it replaced for you under warranty.

Works great and fits snug

I would recommend one of these for your rivian and it's a fair price at 15 bucks.

Works and fits great!

Hydro flask problem solved! This thing fits nicely in the cup holders! It’s a little tight if my wife has the silicone boot on her hydro flask but other than that it’s fine
