Co2 Car Designs

This is a project designing and building a 3D printed CO2 car. The car can be mostly printed with the only requirement for assembly being to purchase small steel rods that act as axles. This project is great way to introduce several skills that can easily be turned into lessons. I will be breaking this thing into 3 parts, each containing a separate lesson. The lessons will touch on skills like physics, math, spacial reasoning and design. My target population is 4th and 5th graders but this can easily be adopted for higher grades. I found that getting my students excited about this project was simple. I taught them the basics of Tinkercad. Then I had them start with a template of a CO2 car and let them make it their own. The initial requirement is to go through the ‘Basics” tutorial on Tinkercad.com at the very least.

This lesson is the first part of a comprehensive CO2 Car unit. This lesson will walk through the design process of a CO2 car. This lesson highlights the design process, aerodynamics and mechanical drafting. Follow-up materials are included that can be used by an instructor to design further lessons in this unit. The follow-up lessons should include: building procedure, safety and use of band saw, drill press & sander as well as proper finishing techniques.

Remember, the CO2 car you’re designing is a dragster — meaning, a streamlined car that competes in drag racing, a sport where two or more vehicles compete to see who can move in a straight line the fastest. Handling is not an issue here.

In the blink of an eye, a CO2 race car does its work. The press of a button, the blast of compressed gas escaping a cartridge, a second of wheels tearing up the track, and it’s over. The excitement is still hanging in the air and the adrenaline pumping, but the race is over.

First comes the design and planning stage, including the evaluation of your available tools and materials and what you can do with them, researching and drawing your dream car, making your dream a reality from a block of wood, seeing if your design cuts the mustard through testing, and perfecting your car. Hopefully, at the end of the project, you’ll have a sense of accomplishment for a job well done.

The car that arrives in the kit is essentially a blank slate. The wood can be crafted into just about any shape you choose using different tools, like small saws and drills. Often, the work is done in a wood shop or a manufacturing classroom. Most kits come with the holes for axles pre-drilled, but on some kits you may have to make your own using a drill press.

Many students have modeled their dragsters after Formula 1 cars, NASCAR racers or even the Batmobile. The best way to design a car is to draw up plans first, build a prototype (if you can) and then move on to the final version.

If you’re in it for the speed, know that the following design factors have an enormous impact on performance: weight – the lighter, the better; aerodynamics – you want your car to cheat the wind; and rolling resistance – less is more. There’s more information about performance factors in the Testing section.

The working drawing is a precise, 1:1 scale drawing that exactly describes your car and its features. Working drawings should have top and side, or profile, views.
