This is a customizable sponge holder with a removable grid for easy cleaning. I designed the holder to fit most kitchen sinks and allow the user to customize the position of it. As you can see in the pictures, you can slide the feet of the holder front to back and clamp it onto the side of your sink or against the wall as I did. It works both ways and it holds perfectly fine. You have to use some force to change the position of the feet but by this the position stays locked in, and you can clamp it better to your sink. You could also use a small hammer to move it more easily. On the inside there is a slope to channel the water to the front and I made the opening a bit wider on the new file as on the picture.
