Raspberry PI case for RGB Matrix Hat

This Raspberry PI case was designed to accommodate the add-on card "RGB Matrix HAT + RTC" from Adafruit. See the product here: https://www.adafruit.com/product/2345

That add-on card was needed for the Raspberry PI LED Matrix Display project.

I made the shell 2mm thick and mounting bosses 5mm high
Sidewall indents for the power plug and HDMI cable are only 1mm thick to ensure the plugs have a solid connection

Screws used to mount the Raspberry Pi:
"#4 x 3/8in"
