Simple model to hold a bar of soap in the shower or by a sink. Scale in slicer based on your soap bars size. Ridges, tilt, and slit added to help excess water drain. I recommend PETG if you plan on using it in the shower, because it may be more durable to hot water. But PLA will probably work fine; I haven't compared shower water temps to glass transition temps.  Modeled with SolidWorks.
