I had a slow day a couple of weeks ago so I decided to make a rubber band launcher to keep at my desk. Excuse the poor gluing job, but it was quickly thrown together. It's made of three, .125" pieces of acrylic glued together. A pull of the trigger launches the rubber band. The screws act as the stops and the pivot point for the trigger. I engraved the insides of the outer pieces to make sure the trigger could move freely once it was glued and screwed together. Like I stated... just for fun!
