Saw there was a contest for a soapdish. I don't think there's a more important distinction that can be made about a bar of soap except where it was last… Just flip from one side to the other to indicate the last point of use!
Dish has an angled surface to drain water and a curved recess to hold the soap in the middle. Print it however you like, but I recommend some support and keeping one of the text sides down towards the bed.
