Star Trek - The Cage - Phaser

I originally printed another version from here (listed below), but found that the handle was a little uncomfortable. I started to redesign it and thought I'd also add a spring based trigger, using a spring from a ballpoint pen.
I designed the last piece of the barrel to have a colour change part way through, changing to transparent when the emitters start.
If you prefer to print the barrel and emitters differently, see "Star Trek Laser pistol by plrmaker7 for the original option. It should fit my handle without any changes required.
Maybe my next on will include lights.
