CO2-CAR

I have been tasked with making a Co2-Car with the following parameters:

custom car build

For my Co2 car, I wanted to make a car that had a main body that would hold the cartridge and have two parallel beams on both sides of the body to contain wheels.

This image shows what been explained above with those lines in the center of both beams being the wheels.

This imagine shows how the wheel will be inserted into the car.

CO2-CAR VERSION 1

After designing the first version it has been deducted that there is high drag and a vortex in the back. The second version will try to solve the vortex.

This was the first test print to see how well the wheel mechanism works. After printing it is clear that the idea has to be ditched.

After discussing with my team it was clear that the built in wheels is a bad idea.

So to solve the problem an axle will go through the entire car that way wheels can be added.

CO2-CAR VERSION 2

With the addition of a smoother back to the car the drag has been brought down.

This is the second test print. This was to see if the axle hole will work and after it was printed it was determined that it does work and that my final print is ready.
