These braces can be used to stabilize the corners of the Mostly Printed CNC. I wanted to adjust my feet but found that added another 6" or so to my 8" leg height. It was wobbling. I put these in each corner and screwed them down. It's rock solid now. Note when you adjust the height of the corner just loosen the leg clamp and allow the leg to slide up and down.Them tighten it back up. I used 10" long conduit per leg.
