Sewer-Cover

thingiverse

I use a sewer cover to block off my bathroom's sewer line. It's always getting clogged, so I designed a new one that addresses its weaknesses. My new design lets water keep flowing into the sewer even if the bottom tank is blocked by using holes on the curved surface. The original cover was completely flat, which meant that when dirt clogged the holes, there was no way to get the water flowing again.
