Every shop has one: the bracket that was never made, the adapter between two things that were never meant to meet, the jig that lives in someone's head. You can't download it, because nobody has built it. Describe it the way you'd brief a drafter — "wall bracket, 120 tall, 90 deep, 5 thick, two slots in the shelf leg, gusset between the legs" — and get a real solid model back, as files you own. Want the holes bigger? Say so. It revises the same part and keeps the history.
Every description is screened before it is built, and the model runs in a fenced sandbox with no file or network access. Your parts stay in your own accounts.
3D design is one extension. Stockroom is another, and so are websites and social media. The Bot is the base: it knows your business, your accounts and your people. Extensions are the pieces we add on top for the work you actually do. If your work is repeatable and you can describe it, we can build the extension for it.
