A kitchen sponge holder inspired by a soap holder design from @piuLAB adapted specifically for sponges.

This holder features a detachable filter that sits inside the frame on 8 raised support tabs. The built-in notch cutout allows for easy removal of the filter while also serving as a drainage hole to keep sponges dry and hygienic.

To prevent the holder from sliding on slick surfaces, I would recommend adding 1" diameter adhesive felt pads to the underside, one in each corner.
