Arc Reactor Sized to Neopixel Ring

thingiverse

This is a 3D-printable arc reactor sized to fit a Neopixel ring. Instructions Printing this should be relatively straightforward. As mentioned in the description, only the battery cover needs supports. The rest should be uncomplicated. Use any fill you prefer, any material you like (just ensure to use white or clear for the lens), as many shells/perimeters as desired, and so on. I experimented with printing a solid clear plastic lens, which produced the most impressive result but was extremely challenging to manage warping. If you can master warping control, then print it solid. You'll find the outcome rewarding. The basic print consists of one battery cover, one lens, one front panel, and one of either the backs (with or without holes), depending on your plans. Bill of Materials: some very small screws with matching nuts. Perhaps locking washers if desired. I used a set of minuscule screws and they claim to be of size 2-56 x 1/4", whatever that means one Gemma one Neopixel ring (size 16) one individual Neopixel mounted on a circular board one 1000uF electrolytic capacitor one 300-500 ohm resistor (within this range) 150 mAh lipo battery with charger (Adafruit). Project dimensions are optimized for this battery optionally, a switch and a button. I used items from my available inventory without providing part numbers. The components fit nicely, making the design feasible to produce in various ways.
