This is for older car models that do not have built-in navigation or bad navigation. My car is old enough to have a cassette player.
This model is made for a Toyota Yaris from 2001 and the phone inside is an S21 Ultra that would otherwise have been sitting in a drawer.
I have sacrificed the original sunvisor to get the swivel part out and modeled a new sunvisor around it. Since this car is really old it’s okay to make these modifications.
So far the driving experience has improved a lot, it is a pretty decent location for a navigation system since you can focus on driving much more easily than having to look down and to the right.

How does it handle the heat of being in a car? The mirror housings I made for my dirt bike got a bit soft just being outside in summer sun (until I annealed them), and inside a car can get pretty toasty. My mirrors were PLA though, if you’re printing with higher temperature material it might not be an issue.
I’ve also printed a few thingies for the car and my experience is, PLA deforms on the first hot day and you can throw it out. PETG lasted 2-3 years for me until it became brittle and broke.
For cars like that I’d just recommend the Android head units that will slide right into the radio hole.
This car doesn´t have an easily removable radio. It is possible to make a fake cassette tape and mount it in there at best. Right now I have a bluetooth fake cassette tape that connects to my phone.
Old Toyota driver and I was blown away when I found cassette to Bluetooth combo I could make work!
