Ultimaker XY Calibration

A small simple 1mm thick motif to test the Ultimaker XY print resolution. ( 36m x 28mm x 1mm).....

Feel free to compare with my results ( see attached image which is a scan of the object on a flatbed scanner with 'mm' ruler alongside).

My interest is in the sharpness of the corners of the motif which ideally should be square and sharp.
