Customizable NeoPixel Ring

thingiverse

Want a special NeoPixel ring, but cannot get right size or they do not have your favorite RGBWW chip? Create your own! …………………… This customizable NeoPixel ring consists of holder, which is used as a jig to assemble individual NeoPixel breakout boards (like these https://www.amazon.com/gp/product/B01K4HCVDC) and also as a case to hold chips together and protect them from damage. Second part is a an optional cover, which can completely enclose ring in plastic and can be glued together with the holder. Using this principle, you can create more complex custom shapes, but that's beyond this simple guide. …………………… For soldering individual breakout boards together I recommend using thin tinned copper wire (not stranded) and thin soldering tip. It looks daunting at first but with all boards aligned and soldering with one piece of continuous wire goes really quickly and you can get it done under 10 minutes. Then use thin (midget) cutting pliers to cut wires between data (middle) pads on each board. Attached pictures should help to explain the whole process (good observer can see I also cut wire between + and - pads which is totally unnecessary, I just got carried away ...) …………………… Ring is designed in OpenSCAD for extrusion width 0.5 mm and layer height 0.2 mm. I strongly recommend to regenerate STL files for different values because of very thin walls. 100% infill recommended, no supports required. Print with clear filament (tested with PETG). …………………… Source file is included. If you remix, please also share your source file.
