This is a simple holder for Samsung S8 phones in a Audi A1 CD drive.
It is adapted from the Iphone 5s car holder by Sally Engineering with little improvement on the fixation by adding extra flaps to have more stability (and obvisouly replace the topp part concerning iphone with samsung S8)
The holder is designed to let free access to the SD card, and is large enough for S8 with a very thin case.
New v3 version : rounded corners.
You may grind a little to adjust to the exact length of your CD drive. Do not grind to much ; the more fit is the holder, the more stability it will have.
