The file 'Flex Innovations Shark Teeth 3D Printer Model' is (stl) file type, size is 3.3KB.
The piece comes with 4 teeth. You will have to glue them together and then stick them onto the plane.
You can also join them in a design software and print as is.
This was designed for the Flex innovations Mamba 10, but I'm sure it could work for other Flex planes as well.
