With your 3D-printed car chassis in hand, it's time to assemble the final race car. Follow the provided instructions
        and utilise your problem-solving skills to bring together all the components. Once assembled, it's time for the
        most exciting part - testing your creation! Prepare for some thrilling races and measure the performance of your
        race car against your team's objectives.
        1.   Once you have 3D printed the car chassis and all the necessary components are ready, it's time to assemble
            the car and test its performance. This step will help you evaluate how well your design functions and identify
            areas for improvement.
        2.   Begin by gathering all the printed parts, motors, wheels, axles, and other components needed for the assembly.
            Make sure you have the necessary tools, and any adhesives required for securing parts together.
        3.   Start assembling the car by attaching the hobby motor to the designated area in the car chassis. Ensure that
            the motors are properly aligned and firmly secured in place.

        4.   Install the axles into the axle holders on the car chassis. If you used straws as axle holders during the prototyping
            stage, slide the axles into the straws. Ensure that the axles are straight and rotate freely without any friction.
        5.   Mount the wheels onto the axles. Depending on your design, you may need to use additional components
            such as washers or spacers to ensure proper alignment and stability. Make sure the wheels are securely
            attached and can rotate smoothly.

        6.   Connect the wiring from the motors to the appropriate terminals on the battery holder or power source.
            Double-check the connections to ensure they are secure and that the polarity is correct. Use tape, soldering,
            or connectors to ensure reliable electrical connections.

        7.   Before testing, ensure that the batteries are fully charged or have sufficient power. Insert the batteries into
            the battery holder and switch on any additional components like switches or LED lights, if applicable.
        8.   Find a suitable location for testing your car, such as a smooth surface table, hallway, or race track. Ensure
            that the area is clear of obstacles and provides enough space for the car to move freely.

        9.   Turn on the power source and observe the car's performance. Note how fast it moves, how straight it drives,
            and any vibrations or issues you observe. Encourage team members to record data during the testing
            process.
        10.   Collect data that will help you evaluate the car's performance and guide modifications to the design. The
            useful  data  to  collect  includes  speed  measurements  using  a  stopwatch  or  measuring  distance  covered
            within a specific time frame. You can also record any observations regarding stability or potential areas for
            improvement.
        11.   Analyse the collected data and discuss it as a team. Identify any areas where the car's performance did not
            meet your expectations or any design flaws that need to be addressed. Consider any modifications to the
            design, such as adjusting weight distribution, changing wheel size, or improving aerodynamics. All these
            could improve the performance.

        12.   Based on the data analysis, make informed decisions about the necessary modifications to the car design.
            Discuss potential design changes and collaborate as a team to implement these modifications effectively.
        13.   If  needed  go  back  to  your  3D  chassis  design  and  make  modifications  and  repeat  the  testing  and  data
            collection steps.

             By assembling and testing the car, you will gain valuable insights into its performance and identify areas
            for design optimisation. Collecting data and analysing it critically will help you make informed decisions
            about  necessary  modifications.  Remember  to  document  your  findings  and  use  them  to  drive  iterative
            improvements in your car design.
