The OpenSourceEV NextGen Phone Mount is the latest generation of the best phone mount on the market for Rivian R1T and R1S. It's a completely redesigned mount that installs at the very top of the driver side or passenger side outboard vents. It's positioned perfectly - easily in reach of the driver or passenger, and outside of the shadow of the steering wheel.

The NextGen Phone Mount is compatible with all three module ball sizes. The 17MM works with most phone mounts, 20MM works with the co-branded Offroam x Peak Designs products, and a 1" size designed for RAM branded items only. If you're not sure what to print, we recommend the 17MM setup.

This design requires an M5 nut and M5x35 flathead bolt. (they are available individually at OpenSourceEV.com should you want to purchase)

We strongly recommend printing this item in ASA or ABS. A high quality / high temperature PETG will likely work but may be less than optimal in summer months as there is tension on the product. Print with supports enabled at 40 degrees and with 20% infill.
