This is a variation of Alfa Romeo MiTo phone holder, redrawn by hand in Shapr3d. Original model taken as reference: https://www.thingiverse.com/thing:4413656
It has a 34mm base for gluing a phone holder, optimised for: āVICSEED Mobile Phone Holder Car Magnet for MagSafeā https://www.amazon.de/dp/B0BHYRC5PG?ref=ppx_yo2ov_dt_b_fed_asin_title
This model solidly hooks into the notch between the vents and is designed to be āinvisibleā. Best printed in black. A bit of "snot" adhesive helps to keep it more stable. Made for my own use case, but hopefully it can help you too.
Shapr3d source file included.
