RPI LCD 16x2 holder + examples

I have a headless RPI3B and many lcd 16x2 with i2c interface, so I wanted to print something that could hold it without screws.

I2c allows to have in this case very few cables as you can see.

I have put also 2 python files that you can use on any RPI to use the LCD.

of course you have to:

1. enable i2c using raspi-config
2. install some python modules in this way:
   sudo apt-get install python-smbus python3-smbus python-dev python3-dev i2c-tools

as usual enjoy.
