4 Inch Corrugated Pipe Grate

thingiverse

When installing a new drain system for your gutters or possibly a French drain in your yard, covering the drain exit pipes is a good idea to prevent small animals from crawling inside and building nests. To prevent this issue, I designed a grate cover for standard 4" corrugated pipe that allows water to exit while keeping things out. The part is printed support-free and can be installed and removed easily. If you ever need to remove debris from inside the pipe, simply take off the cover! Check out my YouTube video describing the design and installation of the grate: https://www.youtube.com/watch?v=IdQoVMijt6Q. Since making the video, I've shrunk the grate "guards" to allow for maximum water flow, ease of printing, and still protect the pipe. Note: I printed this in PETG because it has a bit of flex. Other materials such as ABS or Nylon should work well too. I'm unsure if PLA would work since it's stiffer and more brittle, but let me know if you decide to print it in PLA!
