This design was in response to my niece and nephew playing too much with water balloons and clogging up our drain. Our sink no longer had the metal tabs to hold a typical strainer up so I created this one to lip over the drain on the sink. It uses a 30 mm diameter and 10 mm height for the base portion. The holes are tiny so it does slow down the water some while it is strained through the object. I printed this at 0.2 mm resolution, 25% infill, with raft and supports. It was printed on a Creality Ender 3 printer equipped with a 0.4 mm nozzle.
