Modo▲148I’ve built hardware projects for years, and the gap between “I want X” and “parts ordered, files ready to print” always took weeks. Modo compresses that. Describe what you want (e.g. “a portable CO2 monitor with a display and buzzer”) and it generates: - A bill of materials with real components (MPNs, not hallucinated parts) - A printable enclosure generated from actual part dimensions - Wiring diagrams, firmware boilerplate, and assembly instructions - Design validation (power budget, pin conflicts, mechanical fit) Everything streams in real time as each phase completes. The key idea is…

Examples & Code: * Walkthrough + real prints (bowl, hook, box, door…
