This model was designed as a direct replacement for a broken original rotary control knob (as seen in the comparison photos).
Key Features:
Drive Mechanism: The knob features a central recess designed for an M5 Hexagon (standard 8mm wrench size).
Zero-Play Fit: The tolerance is tight to ensure the hex sits firmly in the plastic wheel without any backlash or wobble when turning.
Mounting: The knob is secured to the device using a central screw that passes through the M5 hex component.
Why I made this: I created this solution because I couldn't find a suitable replacement model that fit this specific mechanism perfectly. Since the original part failed, I designed this version to be robust and functional.
Assembly: Simply press the knob onto the M5 hex nut/bolt head and secure it with the original screw.
I hope this helps anyone with a similar issue! I would appreciate your feedback or a comment if this solution worked for you.
