VW Multifit base for Quad Lock vent mount

Based on the designs from this thing: https://www.thingiverse.com/thing:6322083

I have a quad lock wireless mag charger that came with a vent mount/ball socket arrangement. Rather than using the M8 screw to hold the charger in place I slightly tweaked the design to accept the thread for the ball socket.
Ball socket doesn't need to be screwed in all the way, just enough to not come out.

I also used this as part of my measurements: https://www.thingiverse.com/thing:3943835

Printed on a P1S without supports, though would probably benefit from supports.
Will tweak the "brim" so that it sits more flush with the base at a later stage.
