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 made it out of PETG so a hot summer day shouldn't be an issue.
The battery in the phone won't be too happy with the heat either.
Nice name. I live in the Netherlands so for the next few years summers will be bearable for the most part.
Indeed something to keep in mind when living in a warmer climate. The next model could be something like magsafe.
Don't count on it. On really hot days the interior of a car sitting under the sun can reach petg's glass transition temp. I've had petg prints, also attached to the visor as it happens, soften up and deform in my car.
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.
