Model Rocket V3

thingiverse

As of 5/19/17, I am instructing everyone to print my new design instead of this one, which has not been thoroughly tested by me and is not very good. My latest design includes all the features here plus more. It's my third and most advanced model rocket yet, and it prints in four parts using standard model rocket engines to fly. This version also comes with a second body tube that allows for extra recovery system space and cargo room. I will post pictures soon and ask you to keep an eye on this design as I make adjustments to help the rocket fly better. This is my third model rocket, and here are my previous designs: https://www.thingiverse.com/thing:1643640 and http://www.thingiverse.com/thing:1643618. This was created using a FlashForge printer, and I added it to the FlashForge group to show its capabilities. **Print Settings** Printer Brand: MakerBot Printer: MakerBot Replicator 2X Rafts: Doesn't Matter Supports: Doesn't Matter Resolution: 0.1 or 0.2 Infill: 30-50 Notes: Rotate the bottom file so that fins are in the air, not touching the print surface. Also rotate the cargo hold file so that the male connector is in the air. **Post-Printing** Step 1: Remove all pieces from the printer. Step 2: Clean up the print. Step 3: Slide the connectors together for "Bottom" and "Spacer". Glue these pieces together. Step 4: Slide the connectors for "Spacer" and "Cargo Hold" together. Glue these pieces together. Step 5: Cut a rubber band into one long strip and glue one end to the middle of the cargo hold. Tie the parachute to the middle of the rubber band. Glue the other end of the rubber band to the bottom of the nose cone. Test the tightness of the nose in the cargo hold tube. Add thin layers of hot glue if too loose and let dry before sliding the piece into place. If too tight, sand until correct. Step 6: Straighten a paperclip and glue it to the side-near the very bottom of the rocket (near engine hole). On the other side, glue in a soft wood piece (like a square piece of cork). Make sure the paperclip is centered over the engine hole and insert the engine. Push the paperclip into the wood to keep the engine in place. Step 7: Glue slide rode pieces onto the side of the rocket so that a rod can slide through both of them. Using the Rocket Insert the model rocket engine, igniter, and ignitor holder to the bottom of the rocket and slide it into a launch pad rod. Attach the electric ignitor leads, push the button, and blast off!!!
