Guys this is my new fabricated host, it was easy to build, can be customized for your laser type projects, Body was designed only for RCR123A 3v or 3.6v Batteries. suggestions and comments are welcome
the tube was only made of aluminum tube painted with black acrylic paint matte finish, can be customized the color by the user, in a way of dissambling the unit then ready to paint any color including the head cap and end cap.
i wish i had a local aluminum and glass shop, seeing as i buy lots of glass for aquariums and terrariums, and i would be using aluminum in lasers (oh, i see you resized the pic, thanks)
its ok man, ide like to help anybody whose willing to built this one, actually i began this experiment host when i accidentally put the CR123A in a wasted roof antenna it is build with this kind of aluminum, cuz i dont have any thing to sit the battery in a while : ,then i notice the great thing that may help for my host .cuz the battery moved inside the tube exactly when i bump my back into the antenna ;D
