Make Anything a Laser Pointer

This is a cookie-cutter negative, which, when subtracted from any solid model of a gun (or really anything with a vaguely gun-like outline) makes that object into a laser pointer, with the trigger of the "gun" activating the laser! Designed to work with the model of laser pointer that I got from the Dollar store, but it should work with other types of laser pointers as well (if not, the tolerances are forgiving enough that this model should be able to be sized up and down easily to accommodate other sizes of laser pointers).
