I made a very quick remix as I wanted a soap/sponge dish to add to my custom wash station so this does have grooves underneath that probably arent necessary to anyone else. 

That said this is wider than the original with a slightly thicker base, I don't quite have the finnesse of the original when it comes to the drain plate's funky design. but i hope i did it justice, I just wanted to show how much I admired the original design
