Laundry / Hand Washing / Bucket agitator

This is an agitator for doing hand washing.

I know there's a few that have been uploaded to Thingiverse, but I've found they all tend to have the same issues in common: a long (overnight) print time, structural weak points connecting to the pole, and don't fit the diameter pole I wanted to put them on. So this is my addressing of these issues.

Total print time at .3 res 80mm/s: 6 hours.
Structural integrity: Solid AF at 20% density
Pole OD diameter: 20mm (I use Deta electrical conduit)

Not compulsory, but recommended: 40mm cup head M10 bolt. This further secures the head to the pole
