This print is made specifically to fit over the DJI HD Systems FPV Camera's Lens and offer protection. This lens protector is installed by sliding it onto the lens and won't pop off due to it being pressure fit. Please note, the lens protector will not work on every setup. The lens protector will fit between standoffs that are 23mm from center to center or larger. If your standoff width is narrower then 23mm the lens protector will not properly slide onto the lens. Also, the narrower your standoff width, the less angle you will be able to achieve with the lens protector installed. Printed out of durable TPU and available in a variety of colors. Enjoy!
