I'm looking to build a sliding door or wall that doesn't use the defacto "sliding door" parts, 2874 and 4511. These parts are almost usable for my design: they are thin and have a built-in stopper when using the corresponding "door rail" parts 32028 and 4510. Unfortunately, they are too tall.
Is there a technique to slide a plate, tile, or panel without resorting to using part 30586. I don't think I have the extra width needed by this part in my design.
