52mm filter adapter for GoPro Hero 3 (for bare lens)

This adapter allows you to use any standard 52mm filter on your GoPro Hero 3 lens (without the waterproof case).

It simply presses on the lens (snug fit but I would not use it for extreme sports as it might come loose) and screw in your favorite 52mm filter.

The filter I have shown on mine is a blue filter but probably most popular would be a polarized filter.
