grabcad

The sequence of holes serves to align the carriage at a specified distance; an alternative approach would be to mill only the necessary hole instead of CNC-ing multiple ones. The slot on the left should correspond to the width of your actual ruler, rather than relying solely on the one represented in your CAD model.
