About this 3D model

I made this for the back of one of our fire engines. A little friendly teasing between fire station 1 and fire station 2. Waiting to see how long before station one notices it on the back of their truck. The first profile is only 0.9 mm thick so I could two face tape it right over the top of the original warning sign and it's barely noticeable. :) The second profile is 4.6 mm thick and has six 6x3 mm magnets embedded into it. However our fire trucks are aluminum so the magnets didn't work.
