What's wrong with my prints?

Good morning,

I printed two objects and both of them came with failures.

The first one was the roughness in some areas of the objects, which wasn’t supposed to exist.

The second one were the ticknesses. In the 3D drawing the ticknesses had a certain measure and when printed the objects, these measures increased (about 0,2/0,3mm).

The last one was the interior wall of the cover that suffered a recess.

Is there any explanation for what happened?

I hope anyone could help me!

Thank you!

what software did you model that with?
