Programmable Custom Holiday LED Lights

Unfiltered LED lights are too bright for many purposes. Solution, cover them with small 3D printed bulbs. AdaFruit makes strips of small LEDs with various spaces between the neoPixels. https://www.adafruit.com/categories/183 It turns out hot glue works well to attach 3D hollow printed bulbs to these strips. The bulbs print quickly, and don't use a lot of filament, so you can produce a lot of these quickly. I've included in the files an Arduino programs for randomly adjusting the colors of each NeoPixel.

Print the bulbs hollow and with no bottom.
