Qidi Bed Leveling Nuts - Star Grip

thingiverse

These star grip bed leveling nuts fit the X-CF Pro, X-Max and X-Plus and probably many more printers if they have M4 bed leveling bolts. They are designed to be low profile so that the OEM nuts can be used as locking nuts instead of the little OEM wing nuts. The nuts are composed of two parts. A smaller internal piece that holds a M4 Nylon Insert Lock Nut. This is printed with 100% infill. A larger outer piece that provides good grip / torque, but can be printed at 15% infill. **It is really important that nothing extends below the bed leveling bolts.** There is no extra clearance and anything that extends below the bolts will cause a crash. I continue to use the OEM washers and lock washers between the two nuts, but I am not sure that is necessary. It is best if the M4 nut is a nice tight fit. Printers often produce slightly different model dimensions. You can try either scaling or slight adjustments to your flow percentage to get a tight fit. While I had the bed nuts off, I replaced my springs with 16mm silicone.
