This is the whole Z Axis assembly for a 500W 52mm Spindle upgrade of the 3018 CNC engraver. With this mount you can use the aluminium bracked which the 500W spindle came with. If you want almost 70mm travel distance for the Z axis, also print the rod holder part. You will need longer 8mm rods and 2x 30cm 20x20mm aluminium profiles, but you can keep the lead screw, it will still be long enough.
