Updated!: Balloon Rocket Engines

thingiverse

These are the updated and improved versions of my older balloon rocket engines. All six of the engines have been tested and seem to be preforming better than the original designs. How To Use: 1. Print the rocket engines and then attach the balloon to the larger opening, if necessary you can tape the balloon once its on. 2. Inflate the balloon and then pinch it until your ready. You can either fill the balloon through the engine or take it of and fill it. 3. Once you are ready release the balloon and watch it fly. The more you fill the balloon the less stable it becomes during flight. Recommended Settings: Plastic: PLA (Polylactic Acid) Infill: 5-15% Layer Heights: 0.1mm or 0.2mm Print Speed: 50mm/s If you make this design, post a make I would love to see someone print my design!
