CMF Phone 2 Pro Case including Anti-Agression Whistle

I remade this flat whistle from Jonas Daehnert to be embedded in the CMF Phone 2 Pro back plate. The whistle is positionned on the top of the phone to be as accessible as possible. That way there are no need to search for it. It is always there are and ready to use!

I made the whistle module the same thickness as the camera lenses to make the phone more stable when laid flat camera side down.

The whistle module can be printed in 0,2 mm layers.

I mesured a 103.6 dBA with a sound level meter placed 1 meter away from the whistle.

The whistle module can be printed without support.

I made 0,1 mm tolerance in case the main version doesn't fit for you.

Please give it a 💖 if you like it 🥰
