Filament type for in car / vehicle / camper van parts

I am currently searching for the right filament for parts that I would fit into a camper van. As I am not only planning to print really small caps or hooks but also parts to cover the seat belt for example (about 1m long and 20cm wide), which will be exposed to sunlight and heat (in European summer ~60-75°C), I am quite unsure what to take.
I have a MK3, which will be used for the printing and a housing around my printer (will prevent air drafts but is not able to heat up apart from normal heat bed).

Looking at prusas table, I would assume the best is probably Prusament PC Blend Carbon Fiber? As Prusa states high UV light resistance. But to be honest, I would more like to have a grey color instead of black.
Any hints to which filament to use? is PC Blend Carbon fiber really the best filament type for my application?

RE: Filament type for in car / vehicle / camper van parts

I've got some black ABS parts in/on my car that have been going since late March of 2017.  Couple cupholder inserts, and then a couple small plugs up in the front bumper.  The car even goes through an automated carwash at least two or three times a year.  Plugs up on the front bumper don't look any worse for wear.

 

I've heard that ASA is UV stable and prints similarly to ABS, but I haven't printed in it so I have no real world experience with it myself.

RE:

I have lots of printed parts in my camper.   The pieces which are not exposed to windscreen/window heat (drawer caps, hooks etc) in the camper are in PETG and after one Australian Summer are fine, however for the parts you describe I'd run with ASA, and I'd actually paint to match the surrounding  colour. 

My Dashboard parts are in ASA, sanded, filled and painted and look fantastic - they are exposed to direct sunlight beneath the windscreen and really haven't shown any sign of movement.    I printed with a "Lack" enclosure and a blanket over it to maintain a bit of extra heat, so had a cabinet temperature somewhere in the high forties mostly and it worked.   I would definitely recommend printing a high draft skirt to keep things attached to the plate.

I've had phone holders in my vehicles printed with PETG that held up pretty well in hot summer. However, if you expect the parts to be exposed to direct sunlight you're probably better off with ASA.

Hi guys,

thanks for the answers. So it seems that ASA is the way to go to be safe "enough" and still "easy" to print with good results. That helped me a lot. I am mostly overengineering stuff (out of datasheet values), so getting real life experience is a good way to counter that instinct =)

You might want to give Taulman3D Alloy 910 some consideration.
