Ideally, ribs should be a little thinner so as to not create thick spots –75% of wall thickness for a low-shrink material and 50% for a high-shrink material . Aim for 75% of wall thickness for a low-shrink material, and 50% of wall thickness for a high-shrink material, with a draft angle from ¼° to 1° .
