Astro Pi Sense HAT Standoff

So my Astro Pi Sense HAT arrived without hardware, and after pinging Adafruit (the vendor) and RaspberryPi (the manufacturer) with no immediate response, I got out my calipers and designed this.

Since it goes in an Adafruit case, the bottom holes aren't necessary, so drill out the top holes to whatever size screws you can source locally, bolt it to the Sense HAT, and press the two boards together.
