2d Packing Problem and RC Airplanes | Minimize foam board wastage using Blender + Python + Sparrow

Want to build RC airplanes like a pro while minimizing foam board waste? ✈️ In this tutorial, I show you how to use Blender, Python scripting, and the open-source Sparrow 2D packing solver to efficiently arrange airplane parts on a foam board and reduce material wastage. Instead of manually cutting parts and wasting foam board, we: ✅ Import and trace airplane plans in Blender ✅ Use Python scripting inside Blender to export vertices as JSON ✅ Feed the data into the Sparrow solver ✅ Generate an optimized 2D packing layout ✅ Export the result as SVG for printing or laser cutting For this demo, we trace an F22 RC airplane plan and convert each part into a polygon that the solver can understand. The result? A tightly packed layout that minimizes foam board usage and saves money. This workflow is perfect for: RC airplane builders DIY foam board hobbyists Makers using laser cutters Blender users interested in scripting Anyone interested in 2D nesting and optimization 🔥 Bonus Challe
