I am new to this forum and came here to learn how to correct or prevent the cheese-grater-like surface as shown in the attached picture. This is a window mount combination camera holder/backlight shield.
It was printed at the library on a TAZ 6. All surfaces except the top are pretty nice. It actually feels like a cheese grater, each opening in the surface has a raised ridge around it. I would like to help the librarian resolve this problem. I have looked through a lot of the posts and found nothing like this.
PLA was used for the print which is 127mm x 127mm square.
