For some reason I much prefer to wash my hands with a bar of soap than with a liquid soap gel, and in my apartment I had a bar of soap that would slide all over the edge of my sink and leave a soapy residue everywhere.
I had just started learning CAD at the time and thought of this idea to make my own custom soap dish to serve all my needs.
This was the first time I experimented with 3D printing, and it was a lot of fun. The soap dish came out great and I made two versions of it. Naturally, I gave the better one to my mother.
The first print was done with dissoluble supports, while the second was done with a standard FDM single extruder printer. I also experimented with the Formlabs SLA resin print for this.
I designed the dish to have a grate that rested on the top, so that the bar of soap could sit on the grate and drip whatever watery soapy mixture it had below into the dish. The tolerances were made such that the grate could be easily removed and washed, and so that the soapy drippings could be washed from the dish as well. The bottom of the dish has a patterning of small circular extrusions for a bit of grip on whatever surface it lays on.
These two prints were the updated version I had made. The major difference is that I inverted the shape of the perimeter for aesthetics and so that its easier to read the litter inscription I put on the side.
As seen on the left, this smaller scale print without the grate works really well for keeping together small parts and pieces. Over here I was trying to organize some printed rivets.
