Rough top surface

Hey

I just printed a part, and i got a really rough surface on the top, and the holes in the sides are not intended as well.

The top thickness is set to 0,7mm. Any suggestions on what could be the problem? i tried printing it two times with the same result.

thanks

From the looks of it it seems you’re using a low infill (<25%). Try 30 to 35% and/or 1.05 mm top/bottom thickness.
