This is the Lantern of a member of the Green Lantern Corps.
It links a Green Lantern to the Central Power Battery on Oa.
With it Green Lanterns can properly recharge their power rings.
To do so insert your ring and speak the Oath(follow that attached image for proper motions):
In brightest day, in blackest night,
No evil shall escape my sight
Let those who worship evil’s might,
Beware my power... Green Lantern’s light!
build using thing-o-matic with a 6inch height cap, otherwise either scale down the size, or stop the printer when the cap is done(total of 4in in height)
if you have issues with printing the logo on lantern 2.0, use the "make able lantern" STL
