Diffuser for Adafruit NeoPixel Ring 12 Leds Fitting

thingiverse

This is a custom diffuser for the Adafruit NeoPixel 12 LED Ring. It's specifically designed to snap onto the Adafruit NeoPixel Ring 12 Leds Fitting, available on Thingiverse at http://www.thingiverse.com/thing:424381. For my light painting project, I'm setting all pixels to the same color and want to create a single colored diffused light source. The diffuser is printed in clear PLA filament that comes out a whitish hue. To improve its performance, I sanded down the outside and inside of the circular top using fine-grit sandpaper. I also added several layers of wax paper inside the diffuser to enhance its diffusing capabilities. The original file was approximately 7mm tall but had issues with the "lens" being too close to the pixels. In contrast, my v2 file is about 23mm tall and does a much better job. Update: I've uploaded new files without cutouts on the sides for feeding wires through. If you're using the fitting mentioned above, you can feed your wires through the center of the diffuser instead, depending on your application. These no-cutout versions are available in 7mm and 12mm heights and are currently being used in my capacitive touch lamp with "light shows." Printer Settings: - Printer Brand: Printrbot - Printer: Printrbot Plus - Rafts: No - Supports: No - Resolution: 0.2mm - Infill: 90% Post-printing, scuff up the "lens" of your diffuser with fine-grit sandpaper as described above. Design: I used Tinkercad to design this custom diffuser.
