This LED Diffuser Test Kit is a modular system designed for experimenting with WS2812 (NeoPixel) LED strips and different diffuser types.

The base is a modular box that holds a LED strip, and the top is interchangeable with multiple diffuser designs. Each diffuser comes in several thicknesses and variations, allowing you to test:

  • Light transmittance – how much brightness is lost
  • Light uniformity – how evenly the light spreads
  • LED hotspot visibility – whether individual LEDs are still visible
  • Material and color influence – experiment with different filaments and finishes
Features:
  • 🧩 Modular box design – swap diffusers in seconds
  • 🎛    Multiple diffuser styles – flat, curved, patterned…
  • 📏 Different thickness options for light diffusion comparison
  • 💡 Designed for WS2812 / NeoPixel strips, but fits similar LED strips
  • 🧪 Ideal for experimenting with PLA, PETG, transparent, translucent, or matte filaments
  • 🛠 Fusion 360 project file included – customize the design to fit your own LEDs, shapes, or mounting systems
  • 💻 Arduino test program included – with sample lighting effects for evaluating brightness, uniformity, and color blending
Global parameters - my option
  • Infill - 100%
  • Perimeters - 1 layer
  • Color - Natural color, Prusament PLA Vanilla White
💬Post your own prints, slicer settings, and material choices in the comments!

Your results and ideas can help others achieve better light diffusion and inspire new experiments.
