In relation to Traveller: playing T5 right now, these would be easy to insert using ThingMaker as a guide (say at TL9), and then imagine how dumping a bunch of these in a hostile environment could build a shelter. At higher tech levels, may even build a shelter with local raw materials not imported bricks. At "magic" tech levels, these are nanobots that do huge custom jobs in completely reconfiguring environments.
