Uniform wall thickens
Generally, thinner walls are more feasible with smaller parts rather than with large ones. The limiting factor in the wall thickness is the tendency for the plastic material in thin walls to cool down and solidify before the mold is filled. The shorter the material flow, the thinner the wall can be. Walls also should be as uniform in thickness as possible to avoid warpage from uneven shrinkage.
