I got my MC6600P about 14 years ago and it came with the plastic shell/cover/case (what ever you want to call it). I don't like the plastic case - my machine sits in its table all the time, and the case just gets in the way. Wish you lived close we could see if it fit your machine and if you even like it. I prefer the Tutto trolley for transporting my machine. All I have to do is fit it into the trolley then wheel it to where it goes. Also. it carries other supplies which the plastic case I never trusted to hold the weight of the machine. If you want a cover to keep the dust off - make one or buy the plastic version, so much easier to set aside than the case.
