ROBO3D R1+Plus Quick Release Plate - E3D v6 Hotend (slight mod)

The original was good enough to get my printer back online. There was a little slop/wobble in the nozzle. I found that if I turned the entire thing upside down, cut a notch out of the corner (clearance for belt stay), change the Z height from 6.5 to 6.55 that slop disappeared.
