    My thoughts are to use these to hold corrugated plastic in place during a scape. I will be made with a 3d printer and ABS so that should be safe. I want to use hot glue to hold them in place. Anyone see any issues with this? I intend to leave them in place after scaping​

    Why not use rock?

    Well my thought is that this will hold the substrate back and I'll have better control of the curves in the corragated plastic sheet that butts up against the plastic brackets. This will be used mainly to hold the subtrate in a hill and keep sand seperated from the other substrate.

    Over time, things will mix and the edge of the barrier will be exposed as the sediment settles. Better to see a nice rock than ABS.........
    Now finding the right rock might be tough, but if you are hiding it anyway, then slate etc broken up is easier.
    Most Home Depots have flooring slate that works well.

    Well these pieces are lower than the plastic that will be holding the substrate back (corrugated plastic for curves etc). You still think that even if I start at 1/4 inch substrate higher than the plastic that it will settle that much? I have had plenty of tanks with just one substrate or another but never tried to mix the two in one scape

    Yes, it'll settle over about 2-4 months later.
