This is a simple decorative Stargate SG-1 Power Crystal that lights up.
You insert a LED tea light in the base and that's that!
There are four different sizes of crystals to choose from so that you can mix and match.
Made to celebrate the 20th Anniversary of Stargate SG-1

The base should be printed with minimum infill and bed supports. Any opaque filament will do, I used PETG because why not... If you have any problems with bed adhesion, try adding a skirt/brim with zero offset, 1 layer and 5 outlines.
The crystals are designed to be printed in vase modem, single outline with no infill. I set 1 top and 3 bottom layers. I used transparent ABS for this, you can choose any transparent filament you have. Maybe even a colored one? :)
The base is designed to fit a LED tea light with a diameter of 38mm and 'candle' height of 20mm. Example from amazon: https://www.amazon.com/Flameless-Candles-Realistic-Unscented-Tealights/dp/B00T28FWVS
The crystal has a thin membrane in its base that you need to remove after printing so that the 'flame' of the tea light can fit inside the crystal.
Slot the crystal in the socket and turn on the light.
Enjoy Stargate SG-1! :)
