Struggling to print a cube

We got a SL1 for use in our dental lab, so I've been trying to test different resins to find the % shrink/expansion. To do this, I printed a 25 mm cube. But after the first test, I found that my test cube was not square by a visibly obvious 4%. The sides forming the corner of the cube that was connected to supports were up to a whole 1 mm off. So, I recalibrated the printer and made the cube hollow. That helped but it's still off square by approximately 2% in the same corner.
