A sturdy weathervane for outdoor use with a base that will mount to the end of a 4x4 post..
I created it using SketchIp Free, sliced it with Cura, and printed it on an Ender 3 Pro using blue and white filament.
The settings I used for slicing all the parts except the base were Cura's 'Normal' settings: Layer Height: 0.15, Wallthickness: 1mm, Top/Bottom Thickness 0.6, Infill 10%. For the Base, I used Wall Thickness 4mm so that the top post was more durable.
Use the Exploded view to assemble the weathervane. Take care to assemble the EW and NS correctly as it could be put together backwards. The EW and NS parts have thin edges where they mount to the base. Use care. Then slip the collar on for good support. The VaneBack should snap onto the Arrow to make the Arrow complete. I did not use any glue.
