How does this go back together? [Microstream USB]

Hi! Love this thing! I’ve been using them for years but never dealt with this. If you know well enough ti explain it or if anyone knows of a “tear down” video or something like that. I’ve never warrantied anything through Streamlight but if I can’t get this back together I’ll give them a ring. TIA for any help 🙂

PS: A question I’ve always wanted to ask you guys is what the brightest flashlight is in this form factor. Money is no issue I wish to fantasize 🤤
