Looks like a nice go of it. Also, thanks for pointing out the stl for the belt clamps you are using. I've been meaning to find another solution. The ones I got in my ATI kit are a bit loose.

I would check that all the belts are firmly tightened, and that the V-wheels are tight too, and that the extruder is firmly attached to the carriage. I would try to eliminate any springiness in the attachment of the bed surface to the Y carriage. You can try to adjust the current of the X and Y drivers, too, just in case it's the stepper itself that does not hold the position firmly enough (not likely, but worth a try just to eliminate it as a possibility).
I think the Z axis is fine. I would focus mostly on the Y axis, because that's the one where I can see a problem. Does the face labelled 'Y' look the same, or better?
