PETG in loft space
Hello all. I'm doing some insulation work in my loft and realised that I need ventilation. There is something that I can buy that sorts this by maintaining a gap in the felt to allow airflow.

However this is too wide for the space between the rafters. So I want to print something similar that's does the same thing but I want to print it in PETG. The original is probably printed in ABS but I have loads of PETG so would prefer that.
I live in England where the part will be exposed to low temps in winter, at lowest -15°C with wind chill and highest of probably 45°C when sun is hitting the roof tiles. But it would not be exposed to and UV. Would PETG degrade or would it be good enough and last as long as ABS or ASA?
