A simplified Kancil K4 Air Vent that should be compatible with cell phone air vent mounts; the original adjustable louvres prevent cell phone mounts from attaching.
Requires the rear part of the original air conditioning vent, it only replaces the louvre portion of it.
Vane is angled at 25° as a good balance between flow obstruction and useful adjustment; .f3d file is attached and you just need to modify the "Flap" sketch to change the cross section of the flap (different angles, flat flap, etc.)
Supports are required!
