This is a camera mount for a fatshark 600 TVL camera that easily mounts to the Flamewheel F450. The 4 mounting holes on the bottom line up with the slots at the front and back of the F450. The 600 TVL camera rests in a cradle and is affixed using a 2.5mm zip tie that goes through a slot underneath.I printed this on a MakerGear M2, I used 3 shells, so infill did not come into play. Place the camera into the cradle with the lens fitting through the large hole. A 2.5mm zip tie should secure the camera to the cradle. There is a slot located just under the camera to accommodate the zip tie. This should mount to the slots on the front or back of the bottom plate of the F450 frame. You can mount the camera on the top or bottom of this plate.
