I think the consensus from my research is that PLA sucks for practical prints. If you are going to put a constant load on it or if the location can get a bit hot then the print can fail. PLA is also very rigid which can be good but can also be a negative if you want some give. I’m probably only going to use PLA for more “show pieces” that will only be used indoors and will not take a beating. For things like plastic cases, it’s probably fine.
