shapeoko lift blocks for stock setup

shapeoko lift blocks add 20 mm of height to stock machine so you can add material from the side without dismounting from the waste board. Gives you 35mm of clearance from motor plates. I printed them with 40% infill and 3 perimeters and push thru 1/8" aluminum in one pass at 60mm/min without any flex at mounts. Any more than that and I get deflection at the gantry but not at the mounts. Uses m5 hardware.
