thingiverse
This is a model rocket I designed based off of an Estes Viking I built for Boy Scouts. You will need a launch pad, Estes engines A,B, or C, a rubber band, hot glue (other glue may work but this is what I used), and sandpaper if needed. You will also need a big open area to launch it in since it goes hundreds of feet in the air.
