Here I have a Spawn face light box.

I have used PLA glow blue for the white and PLA glow Green for the eyes, as you can see in the pic this looks good at night.

this can be printed any size you like 

I have added two print Profiles one at full size 180mm  *180mm  *40mm

and one at size 100*100*22

I have use a smaller light for the small box link below.
