About this 3D model

It's a joke sign to make people not want to open your door. I printed this without any color changing systems, I just added a pause by right clicking the layer line bar at layer 27 and manually taking out the filament and putting a different color in You might not be able to scale down model at all with a 0.4 MM nozzle because the hazard symbol might disappear. I attached it to the door with double sided Tape.
