Button Battery Holder for LED

This is a simple compact button cell battery holder for lighting a LED. The batteries I used are Duracell 303/357, also says SR44/SR44W/EPX76.
I needed it to light a rocket that I printed, where the space to fit a battery did not fit a CR232, or AA batteries. Possibly AAA batteries could have fit, but they would have blocked much of the light in the small space inside the rocket.

The rocket that I made is this ornament rocket (http://www.thingiverse.com/thing:39238); however, I did enlarge it to be 5.5" tall.
