Laser Sight for Rubber Band Gun

I printed this http://www.thingiverse.com/make:181686 awesome rubber band shooter and then added a laser sight mechanism to it. =) Dollar Tree has them for a buck. When you hold the shooter in a Weaver grip you can easily lock on to a target for your shot. =)

You can also twist the laser into the bracket so it stays on, but that wears on the batteries and gives away your position. =)
