Stage Light ReRe-Mix For 5mm LED and CR2032 cell
This is a combination of two awesome things:
With the cell it's bright and holds for quite a while (if you dont forget to remove it) :)
Here is a short clip with a RGB Blink LED:

The stl allows for a filament change on the upper layers of the "projector", which I used twice with a "neon" orange (and back to black) using the Swap filament in the Middle-Method. Turns out as a fantastic addition, since otherwise you wouldn't see if the light is working, without it shining on something.
Have fun :) and show your makes!
