Rubber Band Gun, 6-shot, semi-automatic, laser-cut

Have a laser cutter? You can churn out Lyratron XRBGs (Experimental Rubber Band Guns) all day! We developed these pistols as Xmas presents for our bros, and as usual we decided to open source the design. It's a simple 6-shot step-up mechanism. We used 1/8" acrylic glass (plexiglass) and manually rounded the edges of the outer (stationary) band retention notches with a Dremel to improve reliability. Have fun!
