Kitchen Sink Strainer

I tried a sink strainer from thingiverse. It had some issues. By the time it was scaled up for our sink, the holes were too big, and particles could get through and possibly plug the drain.

The handle broke, also the centering piece on the bottom broke.

So I designed my own. It's very robust. I designed it to friction fit our sink, so it wouldn't "fall" out. I tapered the centering piece so it's smaller at the top than at the bottom, also, a chamfer on the bottom to make it easy to insert.
