3D Sink strainer/filter.

This is a strainer/filter for a sink. Diameter of the drain should be about 30mm, but I guess it could work for larger diameters if scaled up.

I figured that if the strainer was made into a hemisphere that it should be able to capture more volume of water than its 2D counterparts. I added sort of a cup/funnel at the top to catch and or divert water.

I found that the pressure of the water on the cup, would make the strainer fall onto its side. I added legs so that it is more stable. Just
