Raised Drain Cover 4.5" OD pipe

thingiverse

Raised drain cover design improved. My initial flat drain would get clogged by grass clippings and leaves during heavy rains. Fits 4.5" outer diameter, 4.25" inner diameter pipe. I used the dimensions off the existing commercial drain cover for a secure fit and it is slightly loose. If you want a snugger fit, apply some dirt on the outside before installation or try 100.5%. I designed it with three walls and a high fill to withstand my weed eater's impact. No additional supports are required. Edit June 2019 I revamped a smaller version, which I prefer more. Initially, I was worried about my weed eater damaging it, but I should have been concerned about the kids. Since they broke the original (Ella!), I remade it shorter and strengthened it slightly. Same slope to the sides, prints the same. New file is drain_cover_small.stl.
