Simple Wind Vane, designed with multiple mounting options. Designed to use a 2d nail or can be drilled out for larger sizes. Spins easy on the tip of the nail with very little friction. Glue or Zip tie nail to mount you select assemble as shown

Great for Drones, hunting, anything else that wind direction can play a part in. Cheap enough to print put them up all over. I suggest red, Safety Orange or Yellow for best visibility.
