I increased the height of mine by 50mm, so I moved the screw holes up by 50mm and the Z stop mount the same. This makes all 3 beam screws available near the top of travel. My first shot, I left them alone and it’s still doable, but you can’t reach the top screw at the same time as the other 2, so I needed to move it all the way to the top for the one screw, then lower it until I could get the other 2. Yes, I needed to adjust the perimeter shape. Kind of a shame, it means that the toe wheel/rollers don’t line up perfectly with the milled piece any more, but it still seems OK to me. I played with one for 300mm rails, but it looks ungainly at that height. I thought that the 200mm rail version was good enough, You can kind of see where I decided to make my changes. (The small holes here are 2.5mm because I thought I might get it laser cut from 12mm acrylic, and then I can tap the holes for 3mm threads.)
