An encoder knob designed to fit Agilent/Keysight's 53230A frequency counter. These knobs seem to be common among similarly sized units, so they should be much more widely applicable to than just this counter. The knob fits a 5mm D shaped encoder shaft, and it has an indent for the "shrouding" of the front panel plastic around the shaft.

One image shows the part against the lighter, rubberized original, and another image shows front and back of the completed part. Prints fine unsupported with good material profiles.
