I often found myself placing a €2 coin near my models when photographing them in order to give the viewer an idea of the size of the model. Some people use a small ruler for the same purpose. So I designed my own dedicated "ruler" set in centimeters.
In the sample model, after slicing the object I placed four M600 commands in the GCode in order to change filament at each centimeter interval. This is entirely optional and is meant for a clearer distinction between each centimeter cube.
