Flagpole ball

I created this flagpole ball (sphere) since mine was damaged last year.  I've also included an end cap for the simple look.  Additionally the end cap could be combined with an another model (like an eagle) as desired.  

I'm not sure how standard the flagpole ends are, but mine was 28.5 mm ID and 36.75 OD with a slight taper.  It goes on so tight it will be difficult to remove.  If you need different dimensions and don't know how to use OpenSCAD, let me know and I can add one for you.
