@msaeger, your extruder is not so bad calibrated.
But it have the same issue than most of direct drive extruders, especialy @ 1.8°.
Definition of feeding is not perfect because the number of steps per millimeter is low. That's why a 0.9° motor is much better for direct drives.
The quality of the driving gear is also important, you want a small toothed one, like MK7/MK8.
The play of your machine is reduced compares at Steve's, that's a good point probably because of the aluminium frame.
Of course, because you have no part fan, overangs and sharp ends are not good.
The Marvin's eyes and handle makes that defaults particulary visible.
May I suggest a turbine fan with a fan duct who cool both sides of the nozzle deposit ?

Hi guys,
This print could have been worst. Usualy you setup with PLA, i believe PETG helps a lot here.
Yes, this par is all about printing in the air. This is a real benchmark part.
This part is meant to be printed right with a perfectly calibrated printer with efficient fans.
The down side of the part can't be perfect without a part cooling fan anyways.
But look at the imperfections on the up side of the part.
We can see the perimeters are not as straight as it should be.
The upperside of the part is not printed realy sharp too.
Probably there's something you can do to improve.
