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. From chapter 5: Fun Festival Hip Pack of our book [Make It, Wear It: Wearable Electronics for Makers, Crafters, and Cosplayers](https://www.ampedatelier.com/make-it-wear-it). If you make one and post on social meda tag it with **#makeitwearitbook** so we can see it!
