I updated the handle to this excellent Star Trek Discovery Phaser, fixed the finger grooves so the curve is better on both the front and rear. I also filled in the holes to allow more glue to bond with the body of the phaser.
IMHO, if you are a guy, you need to scale this phaser up 10-15%. The grip is very small and more suited for a woman's sized hand. In fact, it is so small that I think it's hard to hold.
Stardate - 47634.44, Updated with sliced Phaser body to help those with build volume height issues and when scaling to a larger weapon.
Update - Includes phaser emitter.
