This trick proves useful when fine-tuning Extrusion Steps. Simply position this over your filament and align one end with a reference point on your printer, then mark the other end of the filament. Now, extrude exactly 100 millimeters of filament. If the mark on the filament overshoots the reference point, you need to adjust down the Extrusion Steps. Conversely, if the mark falls short, it's time to boost up the Extrusion Steps. A convenient way to set Extrusion Steps is by incorporating them into your Start GCode.
