Seat Back Attachment System 17mm Ball Mount

This is the replacement 17mm ball mount for the OpenSourceEV Seat Back Attachment System -- a modular, multi-function mounting platform for the back of your Rivian R1S or R1T front seat headrest. It slides onto the mounting plate rail and accepts any standard 17mm ball-compatible tablet or phone holder. It is one component of that kit. A retaining pin is required to secure this attachment to the mounting plate. If yours is also missing, order the replacement retaining pin separately. Printed in ASA for UV resistance and temperature resilience. Made in the USA by OpenSourceEV. Design files available on Printables under CC NC-SA 4.0.
