Two varieties: small spikes and a lavish crystal-inspired variation where each spike is a different shape and size giving the strip variation. The spikes are hollowed making cavities that allow them to fully illuminate. Designed for printing with NinjaFlex filament. Check out our full tutorial with circuit diagram Print with NinjaFlex filament @225 with non-heated build plate. Mount a 60m NeoPixel strip with Permatex 66B silicone adhesive. Wedge some magnets into the sheathing of the neopixel strip with the magnets wrapped in tape to prevent shorting any connections underneath the strip. Match up the magnets so that the strip is held from inside your garment.
