This is a Universal Skimmer Anti‑Clog Insert I made to fix one of the most annoying pool problems: leaves forming a blanket over the skimmer basket and killing the suction. Drop this ring in your basket and the fins break up the leaf mat so water keeps flowing and your pump doesn’t sound like it’s dying. It prints in one piece, no supports, and fits most standard skimmer baskets. The fins stick out about 10 mm which should be just enough to rip the leaves up without blocking flow. If your basket is a weird size, you can scale it a little in your slicer and it’ll still work great.
