Simple ring module

I was looking for the code to generate a ring. Found something usable in the OpenSCAD manual and made a parametric module of it. I thought let's share in case somebody is looking for an easy to use ring script. (-:

If you're just looking for the function, here it is:

module ring (outerRadius = 10, ringRadius = 1) {
rotate_extrude (convexity = 10)
translate ([outerRadius, 0, 0])
circle (r = ringRadius);
}
