RE: First steps in 3d printing

I was looking at some little rack systems for network kit. I've not printed anything that big yet, but it just gives me more options.

I can see I will be buying more filament and need to try other types. I get that PETG is better for things that go outdoors.

I could try Blender, but I know there's a learning curve. I need to work out what I might want to make. For now I'll play with what's in the library.
