REMIXED version of another phone holder.
This version fits many MagSafe iPhone chargers that have a ball narrowed by a nut on the back. You have to remove the ball and tighten the nut through the hole in the holder.
This version, V2, is currently the latest and was printed in clear PETG, vertical position (to strengthen the arms that need to "hug" the vent without breaking).
EDIT: i've added Cable Clamps to help guide charging cable and tidy up.
