Lens petal / hood for the DJI Phantom 2 Vision FC200 camera. Designed to snap on neatly to the rim around the lens, with additional hooks made for firmer attachment with an elastic band.
A number of people on the user groups and forums mentioned that other Lens Petals on Shapeways do not fit the camera firmly, and as a result, here is a product that has gone through multiple iterations and prints to ensure a tight, close fit.
Lens petals and hoods are designed to reduce the interference caused by indirect sunlight. You may have noticed this effect with the FC200 in the form of sunlight flickering through rotors, even when they are not within frame.
