What this country needs is a good soap dish design. First, you need to elevate the soap from the dish so that it does not soak in its own scum. Then you need to keep the soap from slipping off the tray.
It’s a simple design, which I whipped out a couple months ago for Makerbot, before learning that Sketchup doesn’t export to STL. But at least I can paintbucket and smooth it for blog display.
