Okay tried my first mod making a pass thru for my 510/ego gear, and not paying attention with the entire length of my soldering iron, I melted the bijeezus out of the thread end of the flashlight. I tried to dremel it off completely and rebuild the case with epoxy, but that was a really big mess. I ended up grabbing one of my harmonica cases and used that. 4" x 1.5" x 1" and I now have a completely electrical tape wrapped pass thru. So I ordered more DIY parts and then ordered some juice as a second order with the newly earned gift certificate. I am hoping that I get another flashlight so I can try this mod again because I hate being defeated by inanimate objects. I will have my tiny madvapes flashlight 5v PT 510. Oh yes!! I will have my tiny madvapes flashlight 5v PT 510. (insert mad scientist laugh and crescendo of spooky organ music here)
