When over the ear hearing aids are exposed to rain or snow they can become damaged very quickly.
Our solution is a silicon cover for the exposed part of the hearing aid where over the microphone instead of the silicone it has a small piece of Gore-Tex to allow for sound to get to the microphone but no water because Gore-Tex is hydrophobic but breathable.
To make this cover you will need:
-A 3D printer
-3D print the mold that corresponds to the model of hearing aid you are making a case for
-Follow the instructions provided with the silicone you purchased
-Fill each side of mold with silicone, place the hearing aid in the middle and close the mold around it
-Let the silicone set for 12-18 hours
-Cut a small hole in the cover where the microphone is
-Attach the Gore-Tex to that region from the inside of the case
