Stethoscope (with diaphram)

thingiverse

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. Print Settings Printer Brand: RepRap Printer: Athena Rafts: Yes Supports: Yes Resolution: 0.1 mm /layer Infill: 20% Post-Printing Will need black plastic tubing (24 inches), two pieces of tygon tubing (6cm long), a small balloon, and a 2 " OD plastic O-ring. All tubing should have an outer diameter of 1/2". For the diaphragm, cut the nozzle of the balloon off and stretch the remaining balloon across the bottom (larger part) of the earpiece. Hold in place using the O-ring.
