I wanted to have M6 25x25mm interface on the top sled, as well as an option to screw the table from top. It is designed to work on newport corporation equipment.

I also incresed th rod size to 4mm. I used aluminum rods in my build.

Thrid change is I added as a limit stop for the M3 thread an M4 screw. M3 will fit inside the hexagon screw hat. Therfore you will not have wear on your print when moving the sled. Futhermore it reduces the length of the needed M3 screw, which I found hard get my hands on, without limiting the range of possible movement.
