HELP! I am trying to make a two-layered ball. The inner ball is one color PETG (30mm), and the outside layer (about 4mm thick), is a different color PETG. Every time I print, I get sharp fuzzies all over the ball. I've tried everything. When I print the ball as one color, it's fine but when I tried to do the two layers -- it always ends up a sharp, fuzzy mess. Any ideas??
