Discosaurus | RGB dinosaur costume

This is a remix of the spikes by metalnat and adafruit. I came across the LED spikes a couple of years ago, and I knew right then that I wanted to create something similar but with some modifications. I also wanted to hide the wires, add powerful addressable RGB LEDs, and control them using an Arduino. This design can be installed on any type of clothing, but keep in mind that you'll need to drill holes into it. You can get really creative with the Arduino code, making it react to music, cycling through a rainbow, or coming up with other cool effects. You can print everything out of white or translucent PLA, but if possible, I would suggest printing the spikes from both PLA and flexible filament. The bottom houses nuts and needs to be rigid, while the rest of the spike will benefit from being more resilient if it's printed from flexible filament. In terms of hardware, you'll need: - Two M3 nuts - Two M3 screws - Large washers for every spike - A WS2812B RGB LED strip (or something similar) - A 300 ohm resistor to smooth the control signal - An Arduino Nano (or another small micro-controller) - A bunch of cables - A 5V PowerBank to power the system (a 6000 mAh one gets me over 5 hours of continuous use) The standard scale has a 0.4mm wall thickness (single extrusion), and I've also added a 0.8mm version.
