Ordered a new wireless charger. It came with a badly designed vent clip mount, however the bulk of the unit can connect using a ball joint.

My current cup phone type mount used a sliding mount. This adapter converts from that sliding mount to a ball joint type mount.

Updated - Added OBJ with the screw adapter instead of the ball. The ball would break off after a month or two of use. The new screw adapter holds up much better to daily usage.

Printing:
20% infill
Printed face down (ball up), no supports needed in that mode.
I created it first in PLA. Until that version melts in the sun this summer I will continue to use that version. Once it melts I will use a PETG.
