To perform this mod, you have to take out/cut away the dosing system and the portafilter holder. The feet use the existing screw holes in the front, and the hopper just slides in the pre-existing hole. The rubber cap on the hopper is from an old french press style milk frother. I temporally covert the open space around the spout with a piece of cardboard. In the future, I will design a more permanent solution for the cover and a portafilter holder.
