Bike Roof Rack Reminder

Just a simple reminder sign that there are bikes on your car's roof rack. 

Hopefully it won't let you forget about them and avoid potential accidents. 

If you are like me, it probably won't, but hey… at least we tried.

I've included the .f3d file. Feel free to make some changes if you need to.

NOTE: If you are printing it using a heat sensitive filament (e.g. PLA), do not leave it in the Sun, when the vehicle is stopped. It will melt… trust me.
