Please help. I don't understand what I am doing wrong

[IMMORTEN]

My prints keep turning out like this (See attached images) and I seriously don't understand what I am doing wrongPrinter is a Snapmaker 350, fillament is PLA, software is Snapmaker Lurban and designs are made in TinkerCadI have been trying to play around with the different settings...setting infill to 100% and different layer thickness etc.....it has made a little difference but its still looks like anus..I have been experimenting with turning the nozzle temperature up as well an lowering the work speed to 75%, neither of which seem to have made any difference.Please help, I really don't understand what I am doing wrong
