A nice post Kate, I also agree with your point of view that not all makerspaces need 3D printer to be a good makerspace. A library is a place to learn, it is an information center and one cannot argue that it must have a 3D printer. Libraries have been providing lots of valuable information related to research, innovation, and references as well, however they do have lots of makerspace programs available for different people to learn lots of new things. Still they are doing good and will be doing better. Thus, I also say that its not necessary for a makerspaces to have a 3D pinter!
