DIY Print-in-Place Matrix Keypad & LCD Holder

Need a perfect educational Arduino project with a matrix keypad (4x4) and LCD for a school of hobby project?

Key Features:
- 100% PRINT-IN-PLACE, so no need for annoying parts.
- Electronics are ready to slide in, without screws or the use of glue.
- Includes a gap for a Piëzo/Buzzer.
- Includes a lock for opening/closing the enclosure.
- Enclosure opens using a hinge.
- Cable management inside enclosure.

Required hardware:
- LCD 1602 (with or without I2C)
- 4x4 Matrix Keypad
- Arduino Uno (You can also use other microcontrollers if you'd like, I didn't include snap-fit for the Arduino Uno, so you can modify the microcontroller)
- Piëzo/Buzzer (optional)
- Vibration motor (optional)
- Jumperwires (quantity depends on which hardware)

Recommended print settings:
- Tested on Bambu P1S, but other printer should also work.
- Supports: Tree supports
- Best to place the 3D model vertical for the hinges.

Perfect for building a DIY Safe, Alarm System, or Calculator. Just print, slide in your hardware, and you're ready to go!
