Weather Vane with Direction Dial

3D Printed Parts:
The Wind Vane, 4 pieces plus propeller, geometry was downloaded from
GrabCad.com/library https://grabcad.com/library/buoy-7, which I altered.
The propeller I doubled in size and increased the thickness so that supports could be removed without breaking the blades.
The bevel gears were also downloaded from Grabcad.com/library, which I altered.

The rest of the parts I designed from scratch.

The .stl files were exported with a fine tolerance so the threads would print well.
Also, for the threads to work smoothly, add +.12mm for hole compensation for the threads in the X, Y, plane. You probably could also wood or metal screws if you can’t find any #8-32 screws.
