Stethoscope toy

thingiverse

Got a spare filament that's just hanging around? Why not create a stethoscope? Print the 'stethoscope.stl' file and join its parts using your leftover filament. The design includes two filament holes on the body, as well as one in each ear bud. Note, though, that this toy may not function like a real stethoscope - I haven't been able to hear my heartbeat or breathing while using it. For optimal performance, print with a high infill percentage (around 90-100%).
