Right-click the “SketchUp Parts” link, then select save as or Save Target As to save the model to your computer.

Locate the .skp file on your computer - if Windows, the file is likely ina folder named Downloads. Drag the file to SketchUp.

It’s not a very well modeled part, so will need some cleanup.
