I just recieved a Caldera Cone and stove for my Snow Peak 600 mug. While the CC may be a good stable and efficient system, it doesn't lend itself to easy storage. The plastic container that is comes in is heavy, large, and is perfectly sized so that it will neither nest inside the SP600 nor will the mug nest inside it.
Here is what I came up with. Maybe it has been done here before, but I haven't seen it. I cut a plastic cup down so that the diameter of the mouth is a press-fit inside the mug. With this, I can store the stove, cone, fuel bottle, mini-bic, lid and spoon inside the mug, and then press the cup in over the contents to keep everything together and cover the cone. The cup can be pulled off if needed to scoop water etc. without disturbing the rest of the contents, and of course it can be used as an extra cup during meals. The cup is 1oz, but if you don't have a long handled spoon like mine and so don't need the extra height, you could get by with a Solo cup if you treat it gently and save .6 oz. No stuff sack is needed since the cup is such a tight fit inside the mug.
One difficulty was that my rigid aluminum lid would not fit inside, so I made a lid out of flashing as I have seen someone else do here. This lid is flexible enough to fit inside the cone, clips securely onto the mug, and can be pulled back just slightly for use as a pasta strainer if that is useful to you, or as a sippy lid to help keep the contents warm. I think a silicone lid/pot gripper would be a good solution here as well.
This kitchen isn't particularly light (just a hair under 8oz) or compact, but ought to be durable and easy to live with.
