I am thinking about a kind of tent or storage box. It would have a high own bulk and you need to equipt it into a slot like cargo disk to use.
It should work like a combination of disk and silo. You only can place it grounded. it has average bulk and stacks. And main trick would be that you are able to allow other people to use it. Advantage would be in "groupcrafting". A miner uses his "tent" to store his bars. The fitter takes out the bars there and makes units. The units he stores at his tent where a runner easyly can get them. And so on.
It woul be a kind of protected "lay someting to the ground"
