I printed this Prusa PSU cover in black Prusa ABS @ 255°C, 0.2mm layer height without closed chamber. Does anybody know how to get rid of wrinkled surface, scars, gaps and make it nice and clean?
Thanks for any advice.
Why ABS. Pla or PETG would be just as good, and will warp less and have a nicer finish if you slice the model at high quality settings.

Too high temerature.
They look like vibrations. I was similar to that. Observe in places with long straight surfaces. In this case, the belt will resonates. Tighten (if it is too tight to loosen) on the belt.

If it was the temperature, If yes why flawless, next to PRUSA letters? Listen better and logic is not bad if you have …
@Jakab_Gipsz The layers with letters “Prusa” and near was printed more slowly and its had time to cool down. And also, 255° C is wery high temperature. I printing with ABS on 230-240° C.
255 normal for nylon or polycarbonate. And overheating leaves absolutely the same traces.
the part right to the letters is looking like Ghosting. (buhu) comes from high speeds and loose gantrys (or havy printheads) belt tension etc. the “fuzzy” surface below… could be much over extrusion. temperature … Dial in on prob after another…
