The Image is my results from measuring with a digital caliper the test 20mm box, not only is the y axis off by approx. 2.5%, its inconsistent, turning a square into more of a trapezoid than a rectangle, its not very easy to see with the eye, but after printing a more practical test, a 30mm spool holder (thing:295102) was 29.97mm on the x axis, and 20.05 mm on the y axis, which made the threaded part and the nut completely useless

The y axis also bows quite a bit, its hard to explain this so i recorded a video of it moving:
