🧨 My Tiny 3D-Printed Rocket Engine (Propan/Butane + Compressed Air)So I’ve been working on this little rocket engine, and it actually works! It's fully 3D-printed (PLA) and runs on a mix of propane/butane and compressed air. I used a de Laval-style nozzle, which helps the exhaust reach higher speed. 🔧 Specs:• Fuel: Propane/Butane + compressed air• Thrust: Around 20 Newtons (this is just an estimate – I asked ChatGPT to calculate it because I don’t know how to measure it)• Printed in PLA• Nozzle shape: de Laval• Size: 15 cm long
