Thanks for posting! I designed a base for a Trinket and some through-hole neopixel LEDs (https://www.thingiverse.com/thing:3462546).
Here's a sketch that slowly cross-fades the LEDs https://github.com/jrothfeder/tinker/blob/master/VoronoiLamp/VoronoiLamp.ino
How much did you scale this down to fit your base?
Also what infill percentage did you use?
good question :) I think it was 25%. Infill was 20%. Probably could have been less.
Nice. How long did it take?
The lamp about 18 hours. The base around three.
