A replacement front panel encoder wheel for HP/Agilent/Keysight logic analyzers, tested to fit a 16902A and 16823A analyzer, but likely compatible with many more, and maybe other instruments. Fits a 6mm D encoder shaft.

EDIT: also confirmed to work with the 16702.

Prints great face up, PLA will probably do but ABS/PETG is probably more durable. Even flex would likely be fine, not a particularly demanding part in that regard.
