Hello all, I know this is a weird topic but I have no clue where to look. I am new to the 3D printer and have been printing cookie cutters for my wife. When I scale a simple cutter design like a square the cutter thickness increases also. Is there a simple setting in Cura to be able to restrict the cutting edge from becoming thicker? Sorry if this is the wrong place to post this. I just had no idea where to look. Thank you for any help you can give.
