Been playing with the Qi charger design a bit. The final version will be black-- just using white because I don't like it, so use it for parts that'll end up in the trash :P
Charger I'm using:

Matching the shape of the charger test piece:
Installed in the actual shape, charger properly oriented:
Back plate cover with countersunk screw holes:
slot the phone goes into:
back cover attached at 2 of the 9 screw holes:
The entire thing will fit below the lip of the door card (towards the rear) on the e46, which means it'll be 100% invisible once installed unless you're hovering over the door card looking for it. The taller surface will mount against the outside of the door card, so you'll just slip you hand in and be able to touch most of the phone to remove it.
Net iteration is remove the front bottom, as I realize it serves no purpose in holding the phone and should make getting the phone out easier:
