Hey welcome to my design! I wanted to toy around with making a soap holder, they have some amazing ones here. I used some parts from another "jimerb" STL and bam this product is born.

supports are not need however you can use them for the drain spout, I forgot to add them and it still worked out well. If you have any questions or comments let me know, and enjoy!

Updated I made the soap holder wider so it's not so tight for the soap, and the holder for the brush I made wider and longer.
