In this episode I am designing and 3D printing classic static mixer for mixing fluids. In first try I tried to print it horizontally, but surface was not acceptable. Insecond version I modified the static mixer, so it can be 3D printed in vertical position. At the end of the video I am testing it with mixing two fluids (milk and coffie).
