Below, is the link for the feeder thread. You can use just about anything that the elbows will fit in. Someone recently just made one from a Kingsford charcoal holder, because they wanted it to be narrow. I wouldn't say mice couldn't get it there, but if you have the openings hang out over what the container is sitting on, like mine and Ol Grey, it will be harder for them to get in. I also used small L brackets to fasten my elbows to the bucket. I know they will never move, most people use silicone.
