https://www.thingiverse.com/thing:4441076 There are rectangular holes for the nuts to be captured in. They are designed to fit snug, but not tight (aka not fall out, but not required a hammer to install). You will reuse the original limit switch, and it's 2 bolts. You will also have to remove the top gantry brace, and the entire X axis gantry to get this to slide down the outer edge of the rail. The upper and lower mounts are designed to slide freely in the T slot rail.
