Tube for 12/60mm laser - twist caps

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.
