A lid for the shock resistant/waterproof case for the sony action cam that, although not waterproof, does hold the camera in the case and allow sound to get in.
Download the file, print the part. Put it on the camera, Enjoy.
(note that I don't have the batteries with me so I haven't thoroughly tested it yet. Let me know if you have any problems)
