    Don't use PETG. Maybe a high temp Nylon or other filament that can withstand the heat.. it is no UV it is the heat..
    Just googled on 3d filament that can handle heat..

    It depends on the brand of PETG. I made a license plate frame out of black/white Overture PETG a little over a year ago and it still looks just as good as the day it was printed. It has withstood two Houston summers (the recent one with 3 months of 100f+ heat) in direct sunlight with no deformation what so ever. You can also try making it out of PET-CF (not PETG-CF). This filament has an amazingly high glass transition temp. I have printed multiple items that survive 140F - 160f temps with no deformation at all. You just need to have the ability to print 300c and a bed temp of 90c for it.
