Toy Stethoscope

thingiverse

A miniature stethoscope, tailored specifically for little hands. If you're fortunate, it might be somewhat operational. You can sometimes detect a heartbeat if both ends are grasped firmly. To complete this project, you'll require some 1/4 inch / 6.5mm flexible plastic hose. Print two each of "pipe" and "earpiece," and one each of the remaining parts. Absurd warning: This is merely a toy; don't attempt to utilize it as an authentic medical instrument.
