Who needs a case? The 3D Printed Mil-Plastic is he...
For a portable device like this I would be worried about leaving it in the car if it's PLA. You can easily see 70c inside a car on a hot sunny day.
That said, you can heat treat standard PLA to make it resistant to temperature.

Doesn't PLA get dimensionally unstable with heat treating?

It usually is yeah, but you can sometimes get good results. I think it depends a lot on the heat level against the specific print you are doing.

I wouldn’t leave a raspberry pi in a car that gets to 70c due to a very likely risk of damaging the BGA SoC and other soldered components.

The SoC doesn't thermal throttle until 85C. It is not going to desolder from being inside a hot car.
