Raised Drain Cover 4.5" OD pipe

thingiverse

Raised drain cover. My original flat drain would get completely blocked by grass clippings and leaves in heavy rains. Fits 4.5" OD, 4.25" ID pipe. I used the dimensions off the existing commercial drain cover for the pipe fit and it is a loose fit. If you want it to be snug, rub a bit of dirt on the outside before fitting or try 100.5%. I used 3 walls and fairly high fill to give it a fighting chance against my weedeater, we'll see how it holds up. No supports required. edit June 2019 I redesigned a smaller version, which I like much better. Initially I was worried my weed eater would damage it, but I should have been concerned for the children. Since they broke the original (Ella!) I remade it shorter and strengthened it a little. Same slope to the sides, prints the same. New file is drain_cover_small.stl.
