Filament extrusion calibration stick

thingiverse

I'm done trying to obtain precise measurements for calibrating my extrusion stepper motor, so I created a straightforward stick instead. The marks are deliberately indented to last and serve as an accurate way to mark the filament too. The overall length of 120mm is recommended, with markings every millimeter and larger markings at every five millimeters up to seventy-five millimeters. Beyond that, you'll encounter more complex issues than simple calibration.
