Simple cup and string communication device.

Print instructions

Using these two cups and 6 foot of string you can create this high tech social distance personal communication device. Just print the two cups. Note the side print is to allow the diaphragm inside the cup to print. I also set the supports from the base to ensure the cup prints correctly.

When using this device, run the string inside the cup, tie a knot and wrap any extra string on the anchor on top of the diaphragm. The string is run thru the larger hole on the bottom of the cup towards the next cup. When using keep the string taut so sound vibrations can travel along the string. For fun, print two more cups and have a party line by tying the strings together.

NOTE: models are being printed now to ensure correct printability. Small changes may be required as needed.
