thingiverse

This is a 4 engine rocket! It takes 4 Estes B or C engines. We suggest the base with 2 pole attachment bodies then one fin body and a nose cone! The suggested rocket is 21 inches tall, the one in the video is about 40 inches tall! Parts are made to fit snuggly together, otherwise just glue them! General rocket shaped suggestions on what to print! Cone Fins Pole Attachment Pole Attachment Base You can also match and combine how you want! Want a single engine rocket? Here is a link to a single engine rocket by NEATman: https://www.thingiverse.com/thing:13616 Notes: This rocket uses FOUR engines, that means extreme power. For safety reasons please only use the same engines throughout the rocket. Only use Estes B and C rocket engines. Video on explanation: http://bit.ly/Rocket-Video We suggest using this in an open field for damage reasons, chances are that this rocket is going to melt mid flight. PLA melts at ​130-180 °C (266-356 °F) the suggested rocket engine type (Estes B and C) reach much higher temperatures. Stay far back from the launch pad and we suggest wetting the grass because of the fire this rocket produces. We HIGHLY suggest having some sort of protection like a cardboard sheet to put over you if the rocket tilts, knowing there are four engines means there is a high chance of tilting so like I said we HIGHLY suggest this. We are not reliable for any damage/injuries done during your experiment, we are just providing the 3D files.
