the super bright LED flashlight was giving me trouble and I discovered that the spring was glued in place and not providing a good contact to allow the flashlight to work reliably.

I printed 1 part to attach the spring (you'll need to find a way to secure it) and one part for the other end of the battery so it doesn't flop around inside the flashlight.

the little hole was originally intended to hold the spring but i'm only loosely threading the spring into the bigger hole and it seems to hold pretty good.
