Headband for LED light

I'm going to be a construction barrel for Halloween, and I want to have an off-center light. My *hope* is that I can I can stick a button cell battery in the little slot, attach an LED to the battery and the cross-hairs, then cover one or both sides with a transparent reflector.
Even though the headband is tapered, I put the plane of the light holder flush with the plane of one side of the headband... my thought being that things will be off-center but easier to print.
But this is my first ever CAD/3D Print, so we shall see!
