Pimoroni Unicorn HAT Diffuser Grid

I saw a diffuser grid for a much larger Neopixels board and thought, "I want one of those for my Unicorn HAT!", so I made one :)

Simply cover with a piece of paper or similar diffusing material (vinyl plastic also works well).

Warning: I found out the hard way that full power on the Unicorn HAT will warp PLA.

Note: The grid of pixels is not quite square, so this diffuser will only fit in 2 directions. If it doesn't fit first time, rotate it 90 degrees.
