Dimensional parameters of the model adjusted on experimental data: bending modulus at the widest point of the tip versus volume of liquid V in the meniscus. Three tip geometries are represented (spatula, squares; discoidal, circles; pointed, triangles) as well as two thickness profiles ( (solid lines, filled markers) and (dashed lines, empty markers)). The markers indicate particular solutions fitted for every trial batch and the box delimits an area of one standard deviation around average value. (Online version in colour.)
