Calibration Advice Needed After First 2 Prints

Hi! I was using 10 euro cent calibration piece and i got about 0.75mm overall too small pieces (also the outside ). Image file included. Shoud I start checking belts and tighten more first or just adjust X and Y steps. What if x-carriage is loose (bearings moving)? The pieces should be longer then?

Needed 19.75 mm hole diameter
Best for now 19.11mm

This piece is too thin to say nothing about Z, but looks good.

Third one: Now the 10 cent fits with some cleaning. Steps from 80 to 82. Exact calculation was 82.27, but I wonder if only full steps work? Some parts of walls deformed a little and one corner filling is missing some plastic. Just impurities? Pronterface temp was crazy moving from 230 to 207? Slicer: 0.
