Simple and elegant mobile phone holder from Baseus for the air duct which can hold phones from 67-76 mm wide. The holder is silicone-coated on all the surfaces that touch the phone, so that it cannot slide down, but also so that it is not damaged by sitting in it.  The holder is mounted in the air nozzle with two legs/clamps on the back, which are made of metal that silicone coated so that it always stays put.
