Non uniform printing of PLA (shrinking and depending on location even after calibration)

I am trying to print multiple small structures with 1cm diameter circular shape.

12 printings at a time, but only 4 has shape that I designed. It took 14hours to complete all printings and I left them overnight. Most of them became elliptical shape. Please let me know if you have seen this before and if you have resolved this problem.

Printing cylinders is pretty easy. Vertical round holes is much trickier. Please post a photo.

Look at your part in layer view to see if there is something in the slicing stage versus the printer itself.
