FC Cincinnati PopSocket Cover

I designed this for one of my friends using Cura to make the FCC logo from a photo then using Fusion 360 to combine it with the blank PopSocket cover. When I put this into Cura it had weird scribbly lines which I couldn't figure out how to get rid of, but it still prints fine. The print head barely goes back and forth and is hard to see the scribbly lines when it is on the PopSocket. The camera amplifies the lines when you look at it with your eyes it is hard to see them. (see the second photo).
