This Instructable provides the cut sheets for use with a laser cutter, precision cardboard cutter, or you and your choice of cutting implement(s). If you follow it through, you'll have something launchable!
Step 1: Gather materials
- cardboard salvaged from shipping boxes
- duct tape
- drinking straw
- cardboard cutting and assembly supplies (Xacto blade, scissors, cutting mat, tacky glue, two straight/safety pins)
- small hobby rocket engine (we used an Estes A10-3T)
- cladding for engine (usually included with the engine)
Optional: model rocket launch pad and controller, laser cutter
Step 2: Model the rocket
If you want to design your own rocket rather than use ours, use your favorite 3D modeling software (we chose SolidWorks for this project) to model a simple rocket.
We wanted to use the 123D Make web app (see step 3), which can produce the patterns for either folded paper or stacked cardboard (rather than more skeletal, interlocking pieces; that can be done through the desktop app). This meant that the body and fins needed to be separated in the virtual model and will be assembled in cardboard form. The notches in the body are made to accommodate the fins, which are formed in two segments that slot together.
