A sailing friend of mine needed a vertical 'Little Hawk' style wind indicator that can be mounted at the front of their monohull dinghy i.e. where the painter is tied.

I found Kieran's design. But when printed, I found the balance was very tail heavy, so I have modified the design to get it pretty close using 'standard' resolution printing.

The vain should fit directly onto a Little Hawk mount, but I found that 4mm knitting needles (cut down to size) are the same diameter shaft.

I have also published a retain clip (of my design) which can be used:

Filament: Any PLA Your choice, something bright :o)

Notes:

I used PLA, as I'm a newbie, but a more flexible material should take the knocks better..

Also, I would suggest printing upright, as I tried on the side to reduce print time, but the finish on the bottom side where it was in contact with the support wasn't great (see photo of prototypes).

I set supports for over 60 degrees, so that I didn't get one inside the centre hole.
