Here is a quick idea i had for my parents above ground pool the filter strainer was always getting clogged with leaves, bugs, grandkids toys, and causing return issues with their pump so I quickly created this design it blocks all floating particles but has a complete open bottom that allows water to still pass through underneath. They quickly fell in love with it and not having to clean strainer nightly, easily pops in and out for service and what not. Printed in PETG only due to chlorine of pool and direct sunlight would eat PLA in one year. its been out in the elements for about 8months now will zero issues and failures.
