alternativ holder for wind deflector

Added a wind deflector to my Audi A5 Cabriolet (Mj 2011) to support driving it open with 4 people inside. As the original holder did not stay in place while driving a solution was needed. This gives support to the deflector so it stays in place. The wind defelctor is from https://www.auco.de/de/product_info.php?info=p1403{326747}0_ruecksitz-windschott-fuer-audi-a5.html Printing:
