Smoothness Help on my Print

Hey everyone, have been trying to print this simple model out for the last few weeks. I am currently using a Zortrax M300 Dual with PETG filament. I have a HEPA filter attachment on and have been running into some smoothness issues. I have tried multiple things like calibrating the XYZ axis, leveling and cleaning the bed, and even dehydrating the filament and it all seems to keep coming out either with some warping adhesion issues or just simply these weird smoothness issues. Wanted to ask you all to see if there are any pointers or help I could get with this.
