Real simple redesign to extend this for the Eryone Thinker to clear the circuit board on the extruder side of the gantry, also add a top ring to make it easier to align.

Hardware required was 12 M3x16mm (12mm may work) screws and some washers\lock nut for the screw attached to gantry.

Please post makes, it's nice to see the makes.
