FPV风速仪风向标（带轴承）

If you are into FPV you sure have some props lying around.
Why not use one to create a nice wind vane? :-)

You will need a 5" triblade and two of the following ball bearings:
The bearings are hidden and protected from rain.
If you want to go extreme you can choose the following bearing for the prop:
It works perfectly fine for months now and its very seitive to the slightest breeze!
Have fun! :-)
All parts are press fit.
The tail has to be exactly vertical. You can use some glue.
Some very thin oil on the prop bearing will help spin better.
Use white filament or paint it so it does not melt under the sun...
Hubs, bearing holde and prop cover should be printed with 100% infill.
(The logo 'Αίολος' is the Greek god of wind)
