With a watch battery, an LED, and a 3D printer.

Step 1: Do It.

See the pictures above to design your case. All you have to do is design one like this or you can make it different. We made a spaceship one with two holes for LED leads, an a normal one. For a button, I use my finger to push down the extra lead.
I made it to where the battery wouldn't fall out, also pictured above.
Please vote if you like it.
Thanks, it's not hard. All you do is design a spot for the LED(leads are about 0.6mm in diameter) and a spot for the watch battery (about 11mm diameter if I remember right) and make it look cool. 1 tip for 3D printing it though is to be sure it follows the laws of gravity, or put support in it.
