Force measurement

When printing multi-color with the Prusa i3 MMU printer, the filament frequently shifts inside the PTFE tubes. I developed a Spool buffer (https://www.thingiverse.com/thing:3836504) that conserves desktop space. In experiments, it's essential to understand the forces required to move the filament along its entire path. Measuring force is relatively straightforward. Utilize a measuring spoon equipped with a digital scale. Simply replace the spoon with the extension you print on your 3D printer. Use a thin string to transfer the measured force to the attachment. Be cautious not to alter the slope of the balance against the vertical direction of gravity during measurement. The force also encompasses the weight of the attachment. If we desire to calculate the force in Newtons, it's sufficient to consider that 1N equals 100 grams.
