Glowing Cosplay Props

3D print a glowing prop inspired by Sonic the Hedgehog.

Use CircuitPython and Circuit Playground Bluefruit to make a remote controlled NeoPixel Prop!

Inspired by the Chaos Emerald, this 3D printed Emerald snap fits together and houses the Adafruit Circuit Playground Bluefruit.

Bluetooth Controlled NeoPixels

With Circuit Playground Bluefruit you can use the mobile app for iOS or Android to change the color of the LEDs over Bluetooth.

The color picker lets you change the colors and brightness so you can easily adjust the look of the emerald.

Smol, Medium and JUMBO

We designed 3 different sizes so they can be made on a wide range of 3D printers. 

The emeralds are 3D printed without any support material using translucent PLA filament. 

Use natural clear or ivory white translucent PLA for the best looking LED diffusion.
