Case for JY-MCU JY-LKM1638 "8x digital tube LED module" with TM1638

This is a case for the widely available JY-MCU JY-LKM1638 "8x digital tube LED module". The front plate has flexible piano keys to push the module's buttons. The back is just a box with a shelf to hold the board. The front and back friction fit together. Note that in the case back the shelf that goes nearest the buttons is slightly narrower than the others to clear solder joints on the back of the board.

To assemble, put the case front face down, insert the module, then put the back on.
