Stethoscope (with diaphram)

Upgrade to stethoscope design as part of a class project (Advanced 3d printing - MY5777 Michigan Technological University)
Original idea was from a previous student (Brett Barker).
Improved upon the design by changing the ear piece to a diaphragm ear piece with a dual head and the capability to attach a membrane (in this case a stretched balloon) to increase the capability of the device to pick up noise.
