A simple case to house the lip synch robot designed by Sanuki Udon in this Instructable https://www.instructables.com/id/Lip-Synching-Robot/

My version uses an SPI led Matrix but is basically the same as the original, and the unit works well.

Just remember to pass the USB power cable through the back plate before soldering the power wires to the Arduino. Full details of the build can be found at https://roboticshobbyist.com/t/lip-synch-box-project/85
