New to 3D printing (my printer didn't even arrive yet) but I have a few projects I want to start with and I am unsure of the correct or best materials to use for them.

So here are three things I want to print for sure:

Adjustable leg for IKEA BROR. This BROR rack already has a ton of stuff on it, likely in the 20 - 30 KG range so it would need to be a material that can stand that weight. It's also a garage so the expected temperature range is something like 30 to -5C
Some counter top containers to hold things. One of the things I want to hold are laundry detergents. These can be a bit heavy and some detergent can spill, not sure if this can react with the plastic. Indoor use only so the temp range is like 25 to 20C.
Mount plate for a post cap light. I will be screwing these into the post and then the light will lock on to them. The post cap light itself is pretty light however it needs to be able to withstand the elements (snow, rain) and also animals like raccoons and squirrels that might try to pry them off. Temp. range is like 30C to -30C.

If anyone has any suggestions please let me know!

Generic PLA? That is what my makerspace uses mostly

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.
