Parametric Mesh Screen - Round

I created this to make small screens to fit in outside air vents. The goal is to keep insects out while not impeding airflow too much.

OpenSCAD model that I wrote is included so you can re-work the parameters and customize your screen to print directly or use as a component to another model you are creating.

It is an example of using for loops in OpenSCAD to minimize code for all of the mesh lines. Rendering is a little slow, so I would be open to tips you might have on how to make my model more efficient!

If you need a square or rectangle mesh instead, see this model:
