Precision scale knob for multiturn pot

This is a precision scale knob with 100 turns (10×10) for a multiturn potentiometer. Because a multiturn pot takes many full rotations to sweep its whole range, a plain knob makes it nearly impossible to return to a specific setting - this knob solves that with a dual dial: a small window shows the whole-turn count (0–9.9) while the outer fine scale (0–99) shows the position within that turn, giving you a repeatable, precise readout. Designed for a 6mm shaft, it's secured with a fixing screw and includes a locking button to lock the setting in place.
