Sienna 4th Gen Phone Mount

Print with a high temperature and UV resistant material like ASA, ABS.  Designed to be printed on its side, with no supports.  Use a high amount of infill to provide strength to the base of the ball socket.

Ball socket is 17mm in diameter to fit the MagSafe mount below, but could be remixed for whatever size you want.

Use a pry tool to open a small crack in the top dash components and then force the front lip around the curve of the front of the dash.
