A double-sided tool designed for easy cleaning and lubrication of Z-axis lead screws. One side features grooves shaped to match the trapezoidal thread, allowing the tool to follow the screw profile and evenly spread grease along the entire rod as the axis moves. The opposite side is flat, making it ideal for quickly smoothing and distributing lubricant on the surface. This simple maintenance aid helps keep the Z-axis running smoothly and quietly while ensuring consistent lubrication of the thread.
