1. A fit checker as the hero.
Visitors type the length, width and height from their drawing and pick a machine. The part is drawn to scale on that machine's bed, with a height gauge beside it, and the verdict updates as they type, including how many machines on the floor can take the part.
Trade-off: it's a code component, which is harder for buyers to edit than native layers. So every machine, bed size, label and colour is exposed in Framer's properties panel, and the colours are linked to the site's colour styles.
