Desktop Headphones Mount - Multiple sizes

I totally redesigned this Headphone mount for desktop in Fusion in order to have a parametrized size for the desktop width.I included severa lsizes from 19mm to 30mm width in the different build plates.If more sizes are needed, please ask in the comments I will add them.The screw measures 20mm; letting 5 mm inside for adjustment. I can also provide longer screws if required. No support needed; easy print
