Onshape to Blender so I can render!

Does anyone have a workflow for importing Onshape CAD into blender to add texture and then render it? Would love any tips.
At the moment I am looking at exporting as an STL from Onshape, UV unwrapping and applying texture.
If I have duplicate parts in an assembly, is there a way of applying the same UV mapping and texture to the duplicate parts. Kind of like a ‘replace’ feature?

Thanks in advance!
