Exporting with linked geometry?

I’d like to export a model I’m working on to bring into Blender -

Some of the geometry is linked & duplicated 6 times - only one of them shows up, centered.

How can I export everything in the model, as situated?

Bonus question: How can I get the scale to import to blender correctly? I’m working in Millimeters, and thought I had Blender set up properly, but things are coming in far too large.
