How difficult is petg to print?
Comment on Want some advice on which filaments to use

Pla would be fine but petg is my default these days. Petg is a bit more strong and less brittle, which will help at lower temps.
Strength is just as much about design as it is about the filament choice.

I’ve read that PLA will sag over time pretty much no matter what you do. I assume it would be terrible for the first use case. I assume you can’t design around it but I’m happy to be proven wrong.

It’ll only sag if it heats up and starts to deform, like if you leave it in the sun. It’d probably be just fine under a conpressive load like that.

Do you know what temperature range that is? Is 35 to 30C fine?

Yeah. “glass transition temperature” is the term to look up
