Dear @MazaaFIN, thanks for your awesome job, I'm looking this kind of X-Axis for a long time and this design solved my problems, but the thing is I just bought the M5 leadscrews to swap my old threaded rods. Do you have any idea how to modify the leadscrews nut to be M5? Because I don't see any SCAD or similar files in there. My plan is, later on, I can drill a bit when I upgrading to M8 size or maybe re-print the whole design. Many thanks if you can help me about this.
