Windmill -3 Blade Design - Revamped

This is an improvement ove the print-in-place windmill I posted a couple of years earlier. This design uses two 8x22x7 ball bearings available on Amazon as Fidget Spinner bearings. As in the original, the blades can be slotted in the rotor at multiple angles. The stem of the blades is an octagon (typically - 3 different angle configs are possible).  Forgot to add - you will need a 9mm dia x 30mm dowel / 9 mm dia connector rod for standing the model up! Happy printing.
