Cup and String Communications

thingiverse

Using these two cups and six feet of string, you can craft this high-tech social distance personal communication device. Simply print the two cups, taking note that the side print allows for proper diaphragm alignment during the printing process. I also set supports from the base to ensure accurate cup printing. To utilize this device effectively, run the string inside one of the cups, tie a secure knot, and wrap any excess string around the anchor on top of the diaphragm. Then, thread the string through the larger hole at the bottom of the cup, connecting it to the second cup. When using, keep the string taut to enable sound vibrations to travel along the string. For added fun, print two more cups and create a party line by tying the strings together.
