An LED desk decoration shaped like the Facebook angry reaction emoji. Fits a Pro Micro sized Arduino-compatible board. Can integrate with RGB programs like iCUE with the right software: https://github.com/Legion2/CorsairLightingProtocol

Required parts:

• 2 M3x16mm bolts
• 2 M3 nuts
• Short length of 5V addressable LED strip
• Pro Micro or similar-sized Arduino-compatible board
• Paper sheets for improving light spread
• Micro USB cable

Print the faceplate and light guide at 100% infill in a natural or translucent filament. The other parts should be printed in a dark color.

To diffuse the light better, glue a sheet of paper to the inside of the rear shell.
