- Advanced: Large, detailed sets (1,000+ pieces) or custom mechanical designs
- Interest & Theme
- Do you love vehicles, architecture, space, or nature? Pick a theme you’re passionate about!
- Available Pieces
- Inventory what bricks and specialized parts you have. Your project topic should match your existing collection or budget for new elements.
