Pool Bottom Drain Cover - Low Profile

thingiverse

UPDATED Sept 25, 2019 to include both a large single print and a multi-piece print that snaps together for smaller print beds. *** Use at your own risk *** Pool drain covers are safety features that protect swimmers from strong intake suctions that can seriously 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 from a commercial cover, which should accommodate a variety of drain types. The bottom drain cover that came with my pool had a domed / high profile. 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. So I designed and printed this low profile replacement.
