Improved Version:Enhanced handling and smoother rotation compared to the previous version. The handle is now thicker and printed with 100% infill. Reminder:Loosen the screw slightly if the rotation is too tight. Adjust the X–Y contour compensation if needed:Set –0.05 if the screw fits too tight.Set +0.05 if the screw feels too loose. 3. If the screw is difficult to tighten, gently loosen it first, then rotate to tighten it.
