This is an adapter for any of the Holocrons from Star Wars builds that want to use a smaller tea light than the default 1.5" (38.1mm).

I made the Dark/Sith Holocron from here: https://www.thingiverse.com/thing:1194407

However the tea-lights I purchased didn't work as they were too small. They were 1.2" (30.5mm) in diameter.

The tea lights I used have a variety of colors and will cycle between colors. Additionally they have a remote control and changeable batteries.
