Station 3 of 5 on the road every made thing goes down. Someone cuts wood. The first one is never the good one.

One for each object. A greyed-out one is not us being lazy. It is a thing that cannot honestly be done until somebody clears the gate written on it.
Three hundred eighty millimetres nose to tail. Maple body, walnut nose, because the nose is where a hand goes.
IdeaMaterials. The hardest wood goes where the most hands go.

When a shop builds the first Max, we will put up what they got wrong, in photographs, with the measurements. Nobody publishes the first one. It is the most useful one.
IdeaA prototype is a question, not a product.

Nobody has sewn Larry. Everything we say about how he fits together is a prediction from geometry, and predictions about cloth are wrong in small ways that only show up once it is cut. When somebody sews the first one we will put up what did not fit, with the measurements, and what we changed.
IdeaA first article is a question. The pattern is the guess; the sewn one is the answer.
That is the end of this one
The word for what you just did is prototyping.
Prototyping is what a grown-up calls this station on a resume. It is one of five, it always happens in this order, and skipping it does not save you the work. It only moves the work to a later station where it costs more.
