Weird lines and smaller height I finished my first print and it came out like this

 

 



I calibrated all my axis steps and manual movement gives perfect numbers.

I am printing with these slicer settings: 


  
  
  


I don't even know where is the problem to begin searching for a solution. It's my very first print after a couple fails and a lot of calibration to Z axis and bed leveling.

Update the printer without the heatbed as it's an older picture:



The Z axis moves on 2 lead screws and 2 rods with bearings all of which attached to the plate.
I'd say that your axis aren't square, aren't tightened enough and you seem to have overextrusion as well. That would explain why all your layers are wobbly and not neatly stacked on top of each other, why your cube is far being being a cube (the picture of the X face shows it clearly) and the quality of surface finish on the top.

I do not know what kind of printer you are using, but I would advise you to check that the X and Y axis are correctly calibrated and that they're perfectly square, which would ensure that each layer is correctly stacked on top of the previous one to produce a nice cube. And make sure to tighten the axles to avoid the noise in the print due to the vibration produced by the printing. 

As for the overextrusion, you'll need to make more test with your printer and the material you're using, changing temperature, and print speed until you find the right combination that will extrude just enough material through your nozzle.
