Want to start off by saying I'm an idiot. I have a 3.2W 445nm laser I bought a couple years ago and decided to shine it outside around 10pm. While adjusting the focusing piece, I loosened it a bit too far and thus, it fell off. I have no idea where it is so I'm cutting my losses and hoping it's not too difficult to find another one. This piece is still connected, it's the piece that connects to that via spring that's missing. You can probably tell by my definitions that I'm no expert at this. Hopefully it's not too difficult to find. I've included a picture of the laser from a while back with the piece I need: Imgur: The most awesome images on the Internet
