I created this for our bathroom to put sea salt hand scrub in by the sink.

She picked up some when we were in Florida last Christmas so I thought this would be a nice change from the bowl its in now.

I used the sea shell, smoothed it and reduced the mesh resolution considerably. I did some touchup work as well as altered the shape a bit to be deeper and more bowl like.

I used the base from the nude woman thing and sank the shell into it. I reduced the mesh resolution here as well.

I have included the Modo scene file in case you want to make mods to it.

Print each part individually and then use acetone or glue (as whats appropriate for whatever you printed it in) to attach the shell to the base.

If you are using this for what I made it for, print it in something that the oil will not react with. ABS seems to be ok so far but I only have a limited test time with it. I suspect LayBrick would be too porous.
