This is a just-slide-in-your-phone car holder/QI charger I made for my Samsung S7 with thin protective cover AND designed for the connection on the one I already had. I was getting tired of plugging in my phone all the time.
There are only 3 parts :
The holder itself with a cavity for the QI electronics
The QI charger electronics (see here )
The connection plate/cover for the electronics
Since I designed this especially for my situation (dimensions of my phone/cover and my existing holder), I share also the link to the design for the case you might like to create your own version.
Keep in mind that the walls between the spool and the back of the phone need to be quit thin.
I printed this in clear PETG. See pictures.
Print the holder vertically and the backplate flat on the bed.
Keeps well in a hot car. Last days it was up to 27°C over here with lots of sun. No issues.
