Make your own flexible, spiky, glowing accessory using NeoPixel LED strip lights diffused by NinjaFlex flexible 3D printing filament! Magnets let you attach the spikes to anything in your wardrobe. The soft flexible enclosure holds Gemma, the tiny microcontroller that animates the LEDs, and a rechargeable lithium polymer battery.

We designed 2 styles of spike strip — one with regular round spikes and one crystal-inspired statement piece. Whichever you choose, it’ll get you noticed!
