>accurate up to 0.05mm, but read out to 0.01
Does this mean that measuring the same object twice can display two different results within 0.05mm?
>Where are you measuring, as a distance from the bottom?
On the X and Y faces, the calipers are placed perpendicular to the bottom, with the jaws touching both the bottom and the top edges of that face.
I realize now that I could measure across the whole top of the face parallel to the bottom instead of measuring the top with just the tips. However, I went ahead and took multiple measurements all along the cube's Y face, in both orientations.
What do you make of pic related?

Despite the mentioned sagging/expanding of the bottom of the print, measurements parallel to the bottom were much more consistent than measurements perpendicular to it, and in fact the bottom of the cube's Y face was more narrow than the top of it.
According to the calipers, the cube steadily gets wider from the back of its X face to the front of it, except at the end where it somehow gets narrower again. Even if these are not the true dimensions due to the mentioned inaccuracy of calipers, the measurements were consistent with each other when going back and doing them multiple times, so these are definitely the correct relative dimensions.
Given the almost uniform increase in size on the X axis, could it be an issue with bed leveling? Is there any way to improve leveling other than printing a flat test and eyeballing it real good or printing a million test cubes and constantly tweaking it?
