RobotDyn 4x4 Keypad Case - Snap-fit enclosure

thingiverse

This is an effortless way to secure the RobotDyn 4x4 keypad module. The snap-fit enclosure provides a snug fit, while a small opening allows easy access for wiring - this opening also serves as a convenient release point when removing the back panel.\r\n\r\nTwo ledges keep the 4x4 panel firmly in place, preventing it from shifting too far forward. Although there's room for refinement in the snapping mechanism, I've found it reliable so far.
