A 3D-printed decorative cover will take you project to the next level and beautifully diffuse the LEDs on the Circuit Playground Express. Natural-colored or light-colored translucent PLA, such as yellow or amber, is recommended for the LEDs to look best. Translucent flexible filaments or glow-in-the-dark PLA also make a great cover.
