Customizable Herb Support

I found some cool plant supports here, but all it was not really possible to scale them to my different pots without ending up with really thick legs.

So I created my very first openSCAD file which allows you to customize:
* Height
* Width/Diameter
* Number of legs (I recommend 3, but I guess you might want to add more if you print something really big)

Please note this is a bit of a retraction torture-test, but I set the legs to 5mm Ø to make them a bit easier to print even if your retraction is not perfect.

No matter the height the last 1.5cm is determined for the pointy spears.
