4" Sewer Line Drain Cap for Dry Well or Other Projects

thingiverse

I installed a new drain cover in my dry well clean out and it has pretty big gaps - it's the black one in the pictures. While it works fine, I'm concerned that my drywell will get clogged with smaller debris, so I built this cap with much smaller holes in it. As you can see, it's working perfectly. It's designed to fit snugly over a 4.5" wide hole, essentially by sliding it over the existing drain cover that's currently in place. I came up with this design using FreeCad.
