My local squirrel population had destroyed my existing drain covers, so I decided to try my hand at OpenSCAD to get some experience and contribute. This design has been parameterized, and configured for Customizer to help easily shift between different sizes.
I have included a 4" and 6" STL file.
After initially measuring to fit, I sought out some common pipe standards and used them as guidance. The first challenge I ran into was the difference between standard pipe sizes (SCH 90) and drain pipe sizes (ASTM D2729) here in the US. In my case I needed the latter standard, but kept both for others to use as they see fit.
The second challenge came from trying to insert the grate inside of the pipe, and realizing that all of my in-ground pipes were actually using a connector (coupling) to attach. This required the size of the insert to match the outer vs. the inner diameters. I modified the code to support both options. At this point, I have used the Customizer to successfully print both 4" and 6" sizes.

Notes:
**Rotate the Object 180˚ (X or Y) to place the grate surface face down
There is definitely some "bounce" to the grate @20% infill, the second print @50% was very solid.
