About this 3D model
The Z Axis threaded rod for the Anet A8 is too short to reach all the way to the frame, resulting in z wobble. I made this very simple object to press fit to the top of the rods to extend them enough to reach the holes in the frame. To install it, just remove the top plate. You might need to adjust the rod position at the bottom of the motor. Hope you like it. Feel free to leave any suggestions.
