If you have a Travato with a recent model Nova Kool fridge, it probably came with a smaller (25mm diameter) knob. My 2022 G did. If you would like to have a larger knob, this is it! This one is 45mm diameter, 20mm larger. Much easier to turn than the smaller one.
Don't forget to pick up a guard for this knob as well:
