This is the complete assembly of the Z Axis for a 500W 52mm Spindle upgrade on the 3018 CNC engraver. With this mount, you can use the aluminum bracket that came with the 500W spindle. To achieve almost 70mm travel distance for the Z axis, print the rod holder part as well. You'll need longer 8mm rods and two 30cm long 20x20mm aluminum profiles, but you can retain the lead screw; it will still be lengthy enough.
