PLA or PETG for Crockpot Cover?
Good Evening! I wanted to see if anyone had a consensus on if PLA or PETG would be safe for a crockpot cover? It wont obviously see direct food contact but I still don't want chemicals leaching into my food. I recently broke the cover of our crockpot and would just toss it but it used to be my fathers for years who passed and it has some sentimental value so I would like to salvage it if I can 3D print another cover. Any thoughts or comments are much appreciated!

I'd put this squarely in the category of "bad idea" if you actually want to use the pot... temps way too high. For purely decorative purposes, sure

PETG and only for cold stuff (under 50C), unfortunately.
Otherwise you may want to look at ASA and still required post process it in acetone vapor to smooth it to close any pores in it to be able to withstand higher temps (up to 90C).
See my GitHub and printables.com for some 3d stuff that you may like.
Agreed, both PLA and PETG soften at cooking temperatures.
Choose a filament with a higher softening temperature. There are several filaments that would work. For example I have used BioPro from 3DTomorrow for this sort of job with success.
Cheerio,
