Removable soap bar tray

My wife decided to use less plastic and switch to soap bars (hair, body and conditioner). So I made her some bar trays, from plastic (the irony is not lost on me)I designed them so they can easily be removed and they have a space for an insert that says hair, body, after (for conditioner) and all (for the multi purpose bars). They slide onto a hook that is mounted to the wall using double sided tape. In my case this is the best mounting method since ceramic tiles can easily handle the eventual removal of the tape, unlike plastered walls. They let through the water so the soap bar can dry thoroughly. They have no water collection tray so they must be used above the sink, inside the shower, or like in our case, above the bath tub. and yes of course there's hexagons
