...which is why SketchUp shouldn't be used for CAD work.  If you're using 
Windows, I strongly suggest you get DesignSpark Mechanical - it's free to 
use and has a work flow very similar to SketchUp.  If you're not using 
Windows, give the current release of FreeCAD a shot.

When it comes to CAD work, SketchUp is THE worst choice possible.

You should also do your design work in metric if you expect to be having 
parts printed.  Scaling isn't a practical solution because it can 
introduce problems depending on the slicer used.
