Strainer to put in concrete strip drain with 100mm drain pipe. It will stop leaves going into the drain.

If the leaves build up around the strainer, water can still flow up and over the leaves into the open hole in the top with no resistance. Leaves tend to stay low and pressed against the strainer by the force of the water.

I printed it in PETG, but our summers get hot (40+ degrees). It has held up well. The base has deformed slightly due to the hot concrete. I will probably print it in ASA next time.
