I have an iPhone 8+ and I love my car air vent magnetic mount, but since QI charger needs a clear path for its coil to work I had to work around this limitation.
Downloaded Apple accesory design guidelines and with the CAD files I worked around the design limitations.
Included the blueprints for the iPhone 8+ as an example, the same can be done for every phone if you have the exact location of the QI coil
Photos show the whole process, I left a 2mm (3/32") margin over the exclusion zones, so alignment is not that critical.
Used double side adhesive tape to reglue the plate to the iPhone.
Enjoy this project?
