LEGO Engineering Project Plans Prompt Generator
Plan, test, and iterate like an engineer — then export copy-ready instructions.
This LEGO engineering project plans generator creates real-build Technic and system-based STEM projects with copy-ready LEGO-style illustrated instructions, BrickLink-ready bills of materials, and detailed test protocols for classrooms, STEM clubs, and hobbyists.
Use the menus to set engineering goals and constraints, then click Generate. You’ll get clean, copy-ready prompts that already include LEGO-style instruction booklet text, BOM and BrickLink shopping notes. Copy any level or Copy All. Tip: you can expand any prompt box — drag its lower-right corner.
