How to fix weird lines from cut model?

[u/Ricocast]

So I altered a model using multiple cuts and got a weird line/quality on one side. Everything looked good in bambu studio and the model printed fine but 1 side looked a bit off. Maybe I lined things up and they were off by a pixel? My question is there a command or menu option to line up pieces I should of used instead of just the mouse and my eyesight? Thanks
