Pool Bottom Drain Cover - Low Profile

thingiverse

UPDATED October 15, 2020 to include both a large single print and a multi-piece print that snaps together for smaller print beds. **Caution: Use at Your Own Risk** Pool drain covers are essential safety features that safeguard swimmers from powerful intake suctions that can severely injure or trap and drown swimmers if the cover breaks or comes loose, exposing an open drain. This is a replacement cover for a standard pool bottom drain approximately 20cm in diameter. Two different sets of screw hole placements were modeled after a commercial cover, which should accommodate various drain types. The original bottom drain cover that came with my pool had a domed / high profile design. This caused my robotic pool cleaner to "bottom out" when trying to cross over it - it would get stuck straddling the drain with its treads dangling off either side, unable to dislodge itself and continue cleaning. I designed and printed this low-profile replacement to resolve the issue.
