Drain Hole Cover

My sink is old and the drain cover unfortunately rusted and then snapped off due to my son playing with it too much. Thankfully I have a 3d printer and some decent CAD skills, and so this somewhat unique drain cover was born. It functions by keeping the dome off the bottom of the sink using a number of fins which connect the dome to the plug which gets inserted into the drain. As you can see in the animation, the water is able to flow right through the crack between the dome and the bottom of the sink. This is pretty easily printable, but will require some supports.
