It would be a very easy print to make, only question would be durability, not sure what the originals were made of .. probably ABS which is known for poor UV resistance. Easy enough to print materials these days that are UV resistant.
I'll try to do some test prints in the next few days to see what materials I think would work. |
Joke withdrawn..
But when you start vacuum forming, I still get to applaud.
As to why they get brittle, I doubt it was UV... probably just thermally-driven decomposition.. I replaced my duct when I had the dash out many years ago and the old one was more like a cracker than a polymer. So maybe use a material that is rated for the highest use temperature you can process?
