Ooooo I'll have to save this model under my favorites!
I'm not familiar with that 3D printer brand, but the model appears to have some ringing on the sides/surfaces of your prints. Could be due to several things, but my first guess would be vibration (it's usually the case for me). I have a Lulzbot, so if I see this issue usually I can fix it by tightening the bolts holding the bed plate down. With some fine tuning, it'll cut down on what you'll have to sand to get a smooth surface (if that's what you are going for).

I'll be eagerly following to see how the print turns out!
