Here is a remake of my previous design, Matrix of Leadership form Transformers movies. It's LED version :)
Print two main pieces and paint them as you like, then print two hemispheres in clear PLA. Inside you can fit CR2032 3V battery with battery holder and 5mm blue LED. There is a small slot for mini on/off slide switch (commonly available on eBay).
When you finish painting main pieces glue one hemisphere inside each piece, put battery with LED inside and put two main pieces together. Use M2 bolts instead of glue (there are 4 holes in each corner) so you can change battery when needed.
Hope you will like it and if you make it please post pictures :)
