Weather vane to determine wind direction.
To fit AS5600 magnetic rotation sensor and 608Z bearing.
Hub is made up of four parts:
-Cap to hold bearing
-Body to house AS5600 sensor
-Base to attach to substrate with hole for cable
-Cover to add some rigidity and weatherproofing
Vane has a hole for 8mm rod with magnet mounted in end.
I recommend using a de-greased bearing for less friction, and a re-enterable adhesive (siloxane or silicone) to hold the hub parts together and provide weatherproofing.
