Abstract
A split calibration knob can include a lower knob with a lower-knob attachment interface and an upper knob with an upper-knob attachment interface configured to be engaged with the lower-knob attachment interface. One of the lower-knob attachment interface and the upper-knob attachment interface can include a tube with a first press-fit feature and a first positioning feature positioned on the tube. The other of the lower-knob attachment interface and the upper-knob attachment interface can include a hub having an outward facing surface, a second press-fit feature configured to be engaged with the first press-fit feature to secure the upper knob to the lower knob, and a second positioning feature configured to be engaged with the first positioning feature to fix an orientation of the upper knob relative to the lower knob, thereby linking rotation of the lower knob to the rotation of the upper knob.
