A first revision of a laser casing for a brass stock laser module.
12mm main casing, and 10mm thread in cap.
Depending on your printer you might have to use a drill to sand the internals for the module. I prioritized a tight fit to load the module with the front cap attached.
Use any bendable wire (peeled twist wire) to jam between the tube wall and brass module and form a contact spiral for the catode+ on the AAA battery.
Choose your button position, drill a hole and design a button.
