One straight run with a leg out — for the person who never sits upright.
A corner turns the run 90°, and the shape letter follows from those turns. Two right turns make a room with three sides; one right then one left splits a space in two.
Nobody lists this exact shape yet. Ask the workshops that do cover you what they would charge — it costs nothing and commits you to nothing.
Your request goes to every workshop covering your country, and their replies land in one place.
Melange, pill-resistant
Prices only appear once we know where it has to be delivered — a shape one workshop already builds may be out of reach of another.
Nothing is saved anywhere. The address bar holds the whole design — bookmark it, or send it to whoever else has to agree to it.
