Summary

In this chapter, we designed and built a model rocket using a standard paper tube from a paper towel roll. As measuring a paper tube can be challenging, we designed and printed a measurement tool to give us an accurate measurement of the internal diameter of the paper tube.

We used this measurement to design and print a motor mount that we installed and used to give us an accurate outside diameter of the paper tube. Using the internal and outside diameter measurements, we created a nose cone. We designed a fin can using the outside diameter measurement and glued it in place at the bottom of the paper tube. We then finished the construction of our model rocket with a shock cord and parachute.

Although this chapter was geared toward the design and construction of a model rocket, the key takeaway from this chapter should be the lessons learned in designing and printing parts around an existing shape – in this case, a simple paper tube.

In the next chapter, we will...
