9V Battery Hanger with Switch

I love this tree topper this designer made (https://www.thingiverse.com/thing:2629954) and I printed one out last year at the last minute for my tree. I wasn't satisfied with the awesome design, I wanted this Deathstar of Christmas to be FULLY OPERATIONAL. So I rigged up a circuit with a 9V and switch with a LED and drilled it out so I could make it look like it's about to fire. I just hung the battery in the tree with the switch hanging loose too because I made it at like 3am and didn't have time for much else. This year several friends have requested them so I designed a battery and switch housing with a hook on it to hang on the tree for a cleaner and more professional look. The base just snaps into the body, it's not super tough so be careful or be ready to print another. I made about a half dozen of these so far and none have broken even after taken them apart a couple times. The circuit is super basic, just a red LED, 330ohm resistor off the positive side. Then run a wire
