So I was unhappy with the printable Terminal Upgrade token holder and thought I can print this instead, because it looks more bad ass. After printing them all I realized why people print the token holders instead. Because we need to flip those tokens to hide their color.
So I figured, why not just make that colored light as a pin, so we can flip over just that tiny part. I made the pin a bit smaller as the hole, because I didn't wanted it to fit too tightly, since one side will be painted and it already is annoying enough to fiddle that small thing out of that hole even with a loose fit.
Anyhow if you feel the pin could use a bit tighter fit, just adjust it's X and Y axis, but not it's Z, otherwise it will be to large and look like a rod instead of a light bulb.
You could also print with some transparent filaments if you want that bulb look a bit more extra. Maybe half clear and the other half in the color that is needed.
