The file 'Ruler (cm/in) And Dashed Line Straight Edge 3D Printer Model' is (STL) file type, size is 625.7KB.
"Keychain" that can be used to create straight dashed lines or can be used as a ruler in centimeters or inches. I tried to make the design simple and minimalistic, and the holes and slots are wide enough to be used with wooden/mechanical pencils and ballpoint pens.
