Isekai'd with a modern crafting shop

After a fatal cosmic error, a Goddess reincarnates a human into a medieval high-fantasy world, gifting them the Quirky Crafting Collective as compensation. This magical, multi-story modern workshop—complete with top-tier industrial tools and luxury apartments—is condensed into a small, portable cube. Dropped into a damp, dark alleyway of a primitive stone city, the protagonist stands ready to deploy a self-cleaning, high-tech fortress of craftsmanship into a world of swords and sorcery.
