thingiverse

Users can choose from two versions of the 29mm control knob, available in heights of 18mm and 12mm. The 18mm model offers flexibility, allowing users to opt between mounting on rotary encoders or potentiometers with smooth shafts featuring a flat surface, or using them with grub screws for added security. Alternatively, the other version is specifically designed for use with friction fit shafts.
