A much more solid and adjustable Z stepper mount. It uses the spare screws and T nuts supplied with your printer, and keys into the V groove extrusion. Adjustment is independently in X and Y allowing precise alignment of the lead screw for smooth Z travel.
2 or 4 x M3x10 socket head bolts to bolt the steeper to the mount.
2 x M4x10 dome head bolts and Tee nuts to secure the mount to the frame (from the spares supplied with the printer).
Prints fine laying on the flat surface with the rectangular hole. Minimal supports for the slots on the top face are easy and clean to remove.
