Telephone

3D model description

This is a full-duplex update of the venerable tin can & string telephone that lets you talk and listen at the same time. Great for arguments! Each handset has a separate microphone diaphragm and speaker diaphragm connected by lengths of printer filament. It's a great science demonstration of converting sound waves into mechanical vibrations and then back into sound waves. And it is completely 3D printable!
